"Just a quick video of a classic synth. All sounds produced from "normalled" signal routing - no patching. Sorry about the poor lighting and focus, it was late, I was tired and I wanted to get this video made quickly."

"All FOUR oscillators work great and wow this thing sounds huge. I tested a few patch points and they all seem to work, I haven't tried sequencing it because these run at 1.2 volts per octave which isn't what most cv sequencers use. These are real classy and rare, it totally makes you feel like your a mad scientist in a 70's sci fi movie!"

Modular Synth Bassline

YouTube via boobtube356
"VCO-2RM sync patch with pitch modulation on the slave oscillator. The adsr decay and release was varied according to the pitch and emphasis from the A-161. The pitch variations were established using primarily the A160/1 with some influence from a S&H LFO mixed in. Then a four note sequence went to the master oscillator using the A-152. Then the M15 was added using a ringmod, with the same four note sequence going to the M15. Bass kick was added using the MMF-1 with M10 input. Hihat is A-117 amplitude modulated with A-143-3 square using the VCA-4MX. The signal is then level emphasized by the bass kick signal using the MX-4S."

PLL Arpeggios

"PLL (setting 1, and mid range) attempts to track a simple sequence while the master VCO is pulse width modulated in time with the beat. Bass kick is Cwejman MMF-1 sine, other percussion is Doepfer A-117 amplitude modulated by Doepfer A-143-3 square using Cwejman VCA-4MX, and level modulated by the bass kick at the MX-4S. Background sequence is a combination of LFO S&H and Doepfer A-160/1 and A-152 to the VCO-2RM and M15."

"Cwejman VCO-2RM in sync mode. OSC1 square, OSC2 square, RM out to Make Noise QMMG. PlanB M10 envelope modulates the QMMG. PlanB ASR from Doepfer A-143-3 LFO (audio rate) feeds M10 timebase, OSC1 pitch, QMMG modulation depth, and QMMG resonance."

ARP Odyssey Filter Mod

via here on http://www.arpodyssey.com

"Modification for the Arp 4072/4075 filter to expand frequency response.

The four 4K7 current limiting resistors which are connected between

the exponential converter and the four discrete gain stages should

be lowered to 2K2. These are the only 4K7 resistors in the module,

so locating them shouldn't be too difficult.

Another way is to add another set of 4K7s in parallel with

the existing ones. These could be mounted on the solder side of the

board. Beware of possible shorting to other pins."

Tom Oberheim Interview - Questions Open

Mike Welch wrote in to let me know he will be setting up an exclusive interview with Tom Oberheim to be featured on MATRIXSYNTH! If you have any questions you'd like Mike to ask feel free to comment or send them in directly to mwelch at gonzaga.edu. Also, if you are an AV expert in the Bay area and would be interested in helping out, let Mike know.
