Synthrotek Launches Dual Triple Variable Response VCA

via Synthrotek

"The Synthrotek Triple Response Dual VCA uses high quality op amps to give you the sound quality you are looking for in affordable kits and completed units. This VCA has three different response curves per channel: 2 Exponential and 1 Linear. The 3rd exponential response selection (switch at right position) can be modified via two trimmer pots on the PCB. This allows for 3 unique curves per channel.

Intended for Audio & AC use only (DC coupling will not function properly).

Features include:

- Fully opens up at 10 volts with a little extra gain
- 2 exponential and 1 linear response per channel
- Channel 2 is normalled to channel 1
- Compact 4HP sized module
- Kits, complete and PCB/panel combos
- High Quality Op Amps
– Module depth: 1 7/8 inches (4.7 cm)
- Max current draw: 1mA on -12V rail, 9mA on +12V rail"

"The Synthrotek Triple Response Dual VCA uses high quality op amps to give you the sound quality you are looking for in affordable kits and completed units. This VCA has three different response curves per channel: 2 Exponential and 1 Linear. The amplitude of EX2 (switch at right position) can be slightly attenuated via 1 trimmer pot per channel on the PCB. This allows for 3 different curves per channel. EX2 has a slightly more exponential curve than EX1. This VCA operates at 0-5V; a 5V CV input will give you 5V point to point audio output. Use over 5V if you want a super ballsy, loud VCA!

Intended for AC and audio use only (DC coupling will not function properly).

Features include:

- ~5V peak to peak output with a +5 DC CV input

- 2 exponential and 1 linear response per channel

- Channel 2 is normalled to channel 1

- Compact 4HP sized module

- Kits, complete and PCB/panel combos

- High Quality Op Amps

- Module depth: 1 7/8 inches (4.7 cm)

"My first Video of a simple sunday evening patch I played and recorded for myself. I use this for the documentation of my modular patch experiments.

The Drone: Is a Braids with the VOWL model, going thru the RT451 stereo multimode filter, one with HP the other with LP. They go to two channels of the 4ms VCA Matrix. The VCA Matrix is triggered from the Vermona Fourmulator, each LFO 90° shifted, so I get a quadrophonic effect in my studio with 4 speakers around my head.

Kickdrum: I used the Synthrotek ds-m, a wasp from doepfer, a channel from the HexVCA and a envelope from Intellijel. Triggered directly from the ALM Pamela's Workout.

The rhythmic plingplong: Is coming from the OSC-03 form MFB, triggered by the doepfer sequencer, the trigger is multiplied according to the voltage delivered to the A160-5 ratcheting controller.

The snare: Is a noise, going only thru the doepfer VCA in exponentional mode, controlled by an envelope, and then thru a Roland Demora stereo delay.

Happy New Year From MATRIXSYNTH! - A Look Back at 2014

Happy New Year everyone!

I want to start by thanking everyone that comes to MATRIXSYNTH and helps make it what it is - the readers, the supporters, and of course all the sponsors on the right.

THANK YOU and have a GREAT 2015!!!

This site is a labor of love and a ton of work. This site is ultimately meant to be an testament to everything synth in the making. We have over nine years of daily synth history captured here, 119,983 published posts. I can't wait to see what the future brings us in 2015!

That said, here are a few interesting bits from 2014 in the longest post of the year. ;)
