Transistor-82 Lo-Fi Oscillator FM Demo #2

I was contacted by Frederic on Reverb about my Transistor-82 analog percussion module.
He was wondering about the range of the oscillator pitch CV input.
And what it sounds like with oscillator FM.
Be warned, there are some pretty rough sounds ahead.
Audio recorded direct to Tascam DR-05, no added effects.

Transistor-82 Lo-Fi Analog Percussion Synthesizer Overview Demo #1

Today I am proud to introduce my Transistor-82:
a low tech analog percussion synthesizer Eurorack module.
It's been in the works over a year.
Circuit testing has been well...quite addictive!
First I explain the concept of Transistor-82 and how it came about.
Then take a quick tour of the front panel features/controls.
And close out with some audio demos.

Announcing the Transistor-82 Lo-Fi Analog Percussion Module

Thump, hiss, whack, booooom. Transistor-82 is a highly tweakable, retro percussion synthesizer in 14HP Eurorack format. This time around the Transistor-82 is different circuitry than its predecessor. But still has the same vintage charm + adds a ton of features and input CV control over many parameters. I have found this single voice, with this extent of control, can sound like 4 or 5 voices.
The Transistor-82 combines an oscillator with a noise source, along with an optional click transient. The noise source comprises two types: hat and snare (more filtered). With extensive control over decay, pitch, and the Oscillator/Noise Mix – you’ll never run out of old school percussion action.

FEATURES:
Sensitivity Trimmer – controls input trigger response
Decay Knob – controls overall decay
Decay Type Switch – Choose Normal/CV or Short. In Normal position, incoming CV can toggle Norm/Short. Approx 3V is the breakpoint of the toggle.
Oscillator Decay Knob – adds decay time to the Oscillator
Noise Type Switch – Choose Hat/CV or Snare noise types. In Hat position, incoming CV can toggle Hat/Snare. Approx 3V is the breakpoint of the toggle.
Pitch Knob – Initial frequency of the Oscillator.
Pitch CV Jack/Trimmer – control voltage for Oscillator Pitch
Bend Knob – The Decay envelope can affect Oscillator Pitch. 12-o’clock has no effect. CW from 12-o’clock adds to the initial pitch, CCW from 12-o’clock subtracts from initial pitch.
Click Switch – additional attack transient
Mix Knob – controls balance between noise and oscillator
Mix CV Jack/Trimmer – control voltage for Mix

Available mid-march. Be sure to check out my other cool modules available in my Reverb store.

[Roland 909 Day Demo] Juno-1 / TR-8 / RE-20 / 101-VCF / JP6-VCF

Today a special setup for 909 Day!
Featuring some classic Roland circuits.
The highly underrated Alpha Juno-1 on pads and leads.
Getting a dose of cloudy reverb from Strymon Big Sky.
A TR-8 deploying the 909 kit in floor-thumping action.
Smashed to extra crunchy bits in the DBX 166A compressor/limiter.
My RE-20 Space Echo pedal on delay.
The 101-VCF has its input overdriven by Pittsburgh Synthesizer Box.
And the Rozendal CEM3340 VCO going into the JP6-VCF.
Having its resonant arse kicked around my Spring Tank Reverb.
Beatstep Pro on sequencing duty.

Infusor Eurorack Mixer Module

Infusor is a 6-input, Stereo output mixer module. It's loosely based on the MFOS simple mixer w/ some revisions. How did this come about? I'm currently adding a row in my euro case for percussion modules. I like the idea of putting my own 'drum machine' together from various bits and needed a way to sub-mix, say, four of them together - plus an outboard drum machine like TR-8 - without eating up all my desktop mixer inputs. Currently waiting on the trimpots to arrive. I plan on making one to sell. Depending on how that goes I could make a few more in limited quantity.
