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.

Feedback 106 Chorus Demo DIY SMD Version X-Vive Eurorack

Here it is. My fully assembled 106 Chorus by Feedback electronics.
I am not affiliated w/ Feedback or this project.
Just here to give a demo.
And to give some 'feedback' from my build of the surface mount version.

How difficult is the SMD version to build from a bare circuit board?
What are some pitfalls on this build?
How does it sound with the re-issue X-Vive chips?
