Lo-fi Mellotron Style Sampler with a Gieskes DIY hacked Walkman ( Zachteman )

Sound Provider

"A friend lent me a Zachteman for a few days and I took the opportunity to record a lot of stuff with it. The Zechteman is a kind of DIY Mellotron made from a hacked portable cassette player created by the genius Gieskes.It has a keyboard, a vibrato and even a Cv input that controls the pitch and a Gate input that controls the vibrato (Perfect to use it with my Eurorack Synth).
For this demo, I used my Aiwa Cassette Recorder to record a single note with my Analog Synthesiter Moog Werkstatt for 5 minutes and then I used the cassette with the Zachteman to create a melody.
For the last part I added some effects with the Zoia of Empress Effects and I took the opportunity to make a quick Beat with sounds I released on Sound Provider( Analog Now & Techno Now / ) with Maschine Plus of Native Instruments, it allowed me to see that the sample banks of sound provider also works well with the Hiphop 😊😉

How DIY 960 Sequential Controller work

Zygimantas Laurutis

"Module takes bipolar 12 to 15 volt power for operational amplifiers.
Positive rail is regulated down to 5V and power Atmega 328 microcontroller.
74HC595 shift register generates output signals for all steps.
Each step wire powers lamp and rotary switch.
Rotary can send signal to stop or skip busses each have dedicated input on Atmega 328P.
When switch is set to normal, step feeds 3 potentiometers.
Every line of potentiometers collects to a bus, that is amplified with TL074 operational amplifier by the factor of 1, 2 or 4 and goes to CV outputs.
Third line can be mixed with rate control, that uses onboard analog to digital converter.
Every step has dedicated input ports, that can be triggered with button or external signal.

Haken Continuum / EaganMatrix - Using Continuum as a Digital Sound Procesor

EaganMatrix Programming

"Short video to demonstrate how to connect up external audio to be routed into the Continuum to be processed using the EaganMatrix - here functioning as a reverb/delay processor on an unprocessed Synthesis Technology E370 Quad Morphing VCO (but could apply to any Analog source you convert to AES and send into the Continuum). Of course you can do many things with that AES input besides just applying the Recirculator to it in addition to combining it with EaganMatrix sounds (a follow on video will cover more advanced ways to process the external audio)."

Oberheim Matrix 6 w/ The Matrix Theme Ctrlr App Editor

via this auction

"Matrix 6 with 2.15 firmware chip installed!

This allows you to use the Ctrlr App. It’s a VST/AU that really brings this synth to life in the modern age. Tons of presets, really cool random options not found in any other controller. (Click the red pill and a bunch of custom randomization options come up. Click the blue and it brings you back to the init patch.)

G3,A3,B3 keys are not original and slightly different color.

Works perfectly. The innards of this synth are immaculate."

I still have the original PSU (which I will include) as well if you'd want to convert it back to original. All tantalum caps have been removed and upgraded (except for on the original power supply which is not installed).

Never toured of even gigged with, it's been a home studio queen ever since I acquired it in the early 2000s.

Serviced around 2006 by Phil Cirocco of CMS modulars when he was still in Bethlehem, PA. All input and output jacks have been converted to 1/4" Switchcraft. New key bushings on every key around the same time Was just serviced and calibrated by Bell Tone Synth Works in Philadelphia (4/17)."
