Work in Progress



This was recorded without a click track. When this is the source material it must be dealt with sooner or later and usually clear through printing. In the past I have dealt with this type of source material in situ in Cakewalk's staff view knowing that the existing bars were not accurate. For me developing a piece extemporaneously can result in tempo problems because I'm searching and deciding on the fly where to progress to and I'm OK with this. Here I had to adjust the piece to a consistent tempo because I was very sloppy. Finding the first down beat "one" was all I could do. Between the theoretical bars the two, three, four were stretched to fit. For this piece I created a 34/60th of a second counter (actually 17/30 at 30 FPS counter) in an excel spread sheet and used it for determining the SIMPTE time code of the first beat events. I manually edited these first beat events in Cakewalk's Event List and stretched to fit in Staff View the "two, three, four," beats. The exception to this process was the tangential ending of this piece that was dealt with seperatly. So this processing was effectively a re-scaling and partitioning the piece in time without correcting it to the bar lines. Leaving the Cakewalk file still not set to bars as I haven't yet input the click track for 4/4. I may never. I like just working in SIMPTE. Not really.


In this piece the harmonic palette is bi-tonal where the lower tones of any chord are in one key and the upper tones of the same chord are in a different key while some of the tones are common to both keys. The range of the chords types are 9ths and 10ths augmented and diminished. While this provides very rich harmonics it also leads to some fingernails on the chalk board. So in some instances chords or melodic notes use only parts of the chords. Using an online chord analyzer most of the chords where not exactly found and are inversions of a common chord.

Dual 1/3 Octave / Precision Equalizer


known for their good service and low cost products. My first signal processor was an Alesis Midiverb-1. So when it died I purchased the Alesis MV4. This device is versatile and very powerful. The LCD went out in 2010. Not good. The MV4 can still be used. I have eye strain to see the readings sometimes. I found another working Midiverb-1 ($95 eBay) this 16 bit, preset, effects sound processor only has a 10kHz bandwidth.  This combination provides a edgy sound quality that is useful. The Alesis EQ-230 a 1/3 octave graphic equalizer is a helper used to balance out the monitoring system. I use the Radio Shack SPL meter and prepare a 3d graph of the room sampling 20 to 20,000 Hz in 1' squares in the listening zone. I then use the equalizer to balance out the fundamental and harmonic resonances in the sweet spot. It's a lot of work but worth it. Headphones are fine but not enough for me always.

Q49 Midi Controller

It's nice to have a smaller keyboard especially when I'm working on voicing a synth a nearby controller is handy. I got this to update from the Fatar by including mod wheels and velocity sensitive keys. Because I use MIDI not USB, I require the DC transformer (wall wart). The wall wart doesn't come with the keyboard. Multiple emails to Alesis went un answered. They spec the DC volts, amps and barrel connector outside diameter, they do not spec the inside diameter. I'll ended up ordering a 9vDC 500ma transformer on line and splicing in a barrel connector that fit as they used a larger than normal pin. This pin size is normally only used on larger voltage transformers.  The day in the life of a musician trying to work with a vintage system.

Radio Shack Sound Pressure Level Meter


I use this device to measure the audio resonance of a room related to a tonic note. After locating the speakers measurements are made throughout the room. The results relate to the frequency, room dimensions, room’s surface types and, acoustical properties. I use this SPL dB tool to map out locations in the room where the louder and lowest dB’s (volumes) are. For example; a rectilinear room having surfaces of low absorptive will result in a very symmetrical x-y-z grid of alternating low and high dB’s.  At this point listening locations can be balanced and re-measured until you get the best results.

FM Synthesis

FB-01 Doesn't Stink

FB-01  8 voice. No longer supported
    This is the first Yamaha MIDI rack synth I owned. Purchased it at West LA Music in 1986. It is over 30 years old and still fully functioning! This is a ½ wide shelf unit and not very versatile. But, these older FM synths can have a warm, fat, or fuzzy sound that can cut through a mix. These synths can round out the sterile quality of other digital synths by adding a sound quality color to the audio palette. Alone the FB-01 sounds warm fuzzy and somewhat thick but when used in contrast with PCM synths it becomes fuller and richer like a single red brush stroke on a busy oil painting. These FM synths can produce some fat bass.

Sony Subwoofer  SA W2500


I have two of these. The other one is connected to the home theater. Sub woofers are great like a cigar in a non-Freudian way. As in the way a cigar is only great if you are the one smoking it! So are subwoofers great only if it is connected to your sound system. These big subwoofer systems in cars playing a LF bass line;  my first thought is I don't like it cause its some other person's sound system. At least most the kids in the neighborhood won't get run over because they can hear it coming.

Seriously, The Yamaha NS-6490s do emit frequencies well below the stated limits as analogue speakers are our last defense against the ravages of digital sampling. This Sony subwoofer is great in backing up the lowest audio frequencies with the power these body feel frequencies deserve.

When the NS5R came out I was first in line. Remember I like to have multiple synths from the same family for layering and substitution. If you could only get one synth I would suggest the NS5R.

The Korg MS2000R (rack mountable) is a used virtual analog synthesizer that I obtained in early .2012. Real cool. I like the way this sounds better than the BR. I have been going through this testing each controller. I find the BANK/OCTAVE DOWN and the KEYBOARD switches don't work. I'll test later to see if I can affect these functions via MIDI commands.($300 eBay)

Korg MS-20M + SQ-1

This is a true analog synthesizer. Monophonic. The SQ-1 sequencer is CV and the MS-20M can use Midi note on and off commands. Korg products web page.

Korg SQ-1 Instructions I assembled it in a couple of hours. Lots of nuts. It takes a 12mm nut driver- not in the instructions. I am considering tapping out the mod locations off the motherboard.  When I connected the USB from The Tyan Tiger to the SQ-1 an interesting thing happened. Even with the MS-20M and the SQ-1 turned off the Tyan creates some processor activity or video activity sounds that move through the USB to the mixer. The MS-20M is connected to the Alesis MV-4 with a setting that only takes a little sound to excite it.


Korg MS-20M and SQ-1



Here I have painted white latex paint with a two horsehair brush on to the indents of the pitch controllers of the SQ-1. I think they read a lot better… at least I can now see where they are pointed to because before I could not. This paint shows up well when they are lit-up red or not. A real improvement.

Mark of the Unicorn

Timing is everything.

BUGS, ROM, and Battery


    This is an eight port MIDI in/out hub that connects to the computer via a parallel interface cable. The SMPTE, ADAT, video, or audio click coding and sync capabilities are a necessity. With two keyboards and seven MIDI devices this device is working at max, necessitating daisy chaining of some MIDI devices. Acting as my hub controller, my setup needs to be flexible. I can use the tremendous flexibility this device has to offer. I need it. Mark of the Unicorn is on top of the driver issues for all new OS releases. I know this investment will be useable for many years. There is no direct support of the model I have. I have the  model with the RS-232 parallel printer interface. 02/01/2012: I acquired a second MTP AV parallel  Midi hub. With these two devices networked together the rack will be capable of interfacing with 16 MIDI devices. This will be much better and easier to use than dealing all the problems that happen when MIDI devices are daisy chained. 04/01/2012- Ordered ROM chip update from MOTU I will replace the CR2032 batteries at the same time because these won't save any configuration settings. It now looks like I can't network two of these and use W98 as the OS due a W98 limitation. So fine, I could just up grade the computer (dual boot) to XP. But then the Cakewalk won't work. The Pandora's Box scenario that I'm trying to avoid will begin to happen resulting in me having to upgrade everything. I'm trying to stay vintage and limit investment and write off costs. So, I'll tinker at the upgrade but 99% of my effort will be used to reconfigure the MIDI to share MIDI ports between the devices. It will be a little harder to configure and will probably result in some limitations but nothing I can't handle. Without a doubt, I'll end up thoroughly understanding this aspect of these synthesizers.

Protector ( no support) MDX 1800
    As the Tascam DA-38 is a digital recorder, its AD converters can't saturate and absorb extra energy like an analog tape recorder can. Instead these AD devices clip and screech making the recording unusable. A dB limiter must be inline between the mixer and the digital tape recorder to prevent this and is an absolute necessity in the digital recording realm. I like to use the limiter to control spikes while allowing a very hot recording. The Protector is an eight channel limiter that is cabled channel for channel with the eight track DA-38.

Tascam DA-38 Owners Manual



Tascam DA-38 Recording Setup Checklist


    The DA-38 is an 8 track 16 bit CD quality digital recorder. When linked up with the MMC-38 the recorder can sync up with other devices. I set Cakewalk to external SIMPTE Sync and then can mix my six synths down to two tracks and do this four times without having to bounce tracks. This allows a setup, say for a trap set, where each drum and cymbal has its own mixer channel. If I forward Cakewalk to measure 30 the DA-38 forwards to the same position and vise versa.

Tascam D-A38

The MMC-38 is designed to offer MIDI control over the DA-38. This will convert MMC to DTRS transport commands, and convert tape time (ABS) to MTC and SMPTE time code. This is ideal for giving sequencers, or basic digital consoles transport control over the DA-38, and synchronizing MIDI equipment.

QSC GX3 Power Amp


qsc gx3 power amp

Rear rack brackets This amp, like all power amps, is heavy.

A device this heavy shouldn't be mounted to a front rack only application. So I purchased their rear rack brackets. Not so user friendly. I had to use a 10/32 Tap because the flanges are not threaded. A real disappointment. Building a rear bracket in a cabinet and installing the component is tricky.


After The Crown DC150 blew out the studio monitors and fried,  I needed a new power amp & mix speakers. This is the one I picked. I hope it will serve me well. It puts out more power than the speakers can handle. So it will never be turned up above the mid mark of 10dB of attenuation.


	{\nabla^2 u -\dfrac 1{c_0^2}\frac{\partial^2 u}{\partial t^2} + \tau_\sigma^\alpha \dfrac{\partial^\alpha}{\partial t^\alpha}\nabla^2 u	- \dfrac {\tau_\epsilon^\beta}{c_0^2} \dfrac{\partial^{\beta+2} u}{\partial t^{\beta+2}} = 0.}


Attenuation expressed in decibels of relative power. A 3dB pad reduces power to one half, 6dB to one fourth, 10dB to one tenth, 20dB to one hundredth, 30dB to one thousandth and so on. For voltage you double the dB's so for example 6dB is half in voltage.

I made this router switch to enable some basic routing functionality for monitoring and recording.  See the Studio Schematic for details.  The switching of any circuit requires moving two DPDT rocker switches, one for each channel. I wired this parallel, without a common ground, to eliminate the potential for ground hum or bucking battery. In the center position, the circuit is dead ended. Pushing up or down directs the source to the destination chosen. This switch saves a lot of hassle getting into the back of the rack and moving cables around all the time. This device introduces no measurable loss, no bandpass filtering, and introduces no noise into the audio spectrum.

The Fender Rhodes Mark 1 Suitcase and Stage 73 Key Electric Pianos


I purchased my first Fender Rhodes at Broadway Piano, on Broadway a few blocks south of the Denver Art Museum. I think Joe Onofrio owned the store.  Fender Rhodes Case 73 in 1973. 

I spent my all my spare time, after the main day gig, working my licks. I learned about music theory with the help of this wonderful instrument in my one room apartment and with the help of my elementary orchestral music instructor at night and on weekends at the theatre four blocks away. There I had to do the clean up of the burnt rods and lunch bags, every night,  in that old-town theater in North Denver where I  learned to run a projector, change reels, replace rods and splice film too! 

The quality of this particular piano was very good. Every key was balanced and of equal weight. Wonderful light action produced a mellow vibe thing, yum and restful. Forceful staccato strikes produced a real funky tonal effect. Simply explained as sexy and expressive like man in the machine age. The vibrato effect was pulsing and complex like a Leslie Speaker. Great with rhythmic and funk pieces and expressive with soulful slow pieces. 

I now own two of these, a Stage 73 and a Suitcase 73.

My Computers

See the Tyan TIGER 100 Dual Pentium 2x 400. This computer serves as the Midi controller for the entire system and the digital recording system, the final mixing stage, and where the CD is burnt. .

Studio Monitor Series Stereo Headphones


I'm now using Yamaha HPH-MT8 headphones. One thing I really like about these; the cable plugs into the headphones. They are not hardwired. So when I'm finished where I'm  sitting on a stool working with a component low in the system auditioning with the headphones and get up not realizing I have a foot on the cable they don't break or rip my ear off. They just come un-plugged. NICE!. What I don't like is that they are too heavy for the amount of padding on the crown. They can bother my noggin top.  Not a show stopper. They reproduce sound accurately in the high and midrange but roll off in the low frequency like all small diameter plates do. They are great for practice, composing, and a part of mixing.

Boot Sequence: Korg SoundlinkDRS 1212 I/O



I'm rebuilding the rack here. It's easier to set a rack over when adjusting the equipment in a rack and you are doing it by yourself.  Several components have not been installed here yet. This is the first photo of the Mackie in the rack. The pencil tray and handle at the bottom of the Mackie serves no purpose when the mixer is rack mounted. I tried to remove it. After disassembling the component shell I found out that the entire board must also be disassembled. A much harder and more dangerous task than I will take on. So, I proudly am the owner of a vertical pencil tray and will defend its purpose whenever challenged.

Eguipment Rack Information



Rack 3


This is a mid-sized equipment rack with 42" rails.

I'm using pre-finished birch plywood, pocket screws, and Baltic birch plywood. The casters are from Harbor Freight. The plan is to build one more of these and a two to three more of the two footers.  The objective is, with these and a table I can set up a more user friendly workspace. A four sided open box isn't strong. Install the equipment in it and it's a five sided box, very strong. I have installed two power strips, in series, for all the equipment.

O' the joys of vintage gear.

To be able to get to the point where maintenance of vintage gear is possible it takes, luck, care, and MOVs (metal-oxide varistors).


All the devices that have user ROM allocation for user settings to be saved in have batteries to retain the information. Usually lithium type coin batteries. Some have battery holders and some are direct soldered. All of these batteries need to be changed out.  The devices with batteries in battery holders are a piece of cake. The devices that require de-soldering and re-soldering are, of course, more difficult and have a higher risk of beflamadoodling which renders them knackered and useless. I'm looking into what it would take to insert a battery holder to eliminate more soldering in the future.
