"Clean, Serviced and calibrated sh-101! Clean battery compartment. New power supply included. Plays and sounds great. There was a small crack under the keys which is strong and reinforced - that's the only thing that kept us from listing as excellent.

Tubbutec Midi, which we stock, is available for install for a fee."

"Jam with Drummertime and Brainstep in a small Palette case.
Demonstrating how such a small case can be suffient to get a nice Acid jam running and shows the live performance features of Drummertime.
https://tubbutec.de/drummertime/

Drummertime is controlling the 6m0d6. We have 3 patterns that are arranged in a 8-pattern song.
In one of the patterns, a flam eefect is triggered.
I am using the MUTE mode for performance and change to random play mode and back to normal at some point.
Brainstep is generating filter and VCA envelopes +, LFOs,
one of Brainstep's LFOs is used as the VCO (!).
Additional drum an vocal sounds are also generated by Brainstep.

Hello Drummertime - Tubbutec

video upload by Stazma and Tubbutec

"This was the very first patch I did when I got the Drummertime in the studio (30 minutes ago hahaha). I just played around and that's the result. Bass triggered by the accent, drums from the amazing 6mod6 also by @tubbutec and @lpzwmodules

You can connect these two with special cable on the back so you don't have to use patch chords but well I was in a hurry and wanted to jam ;-)

More infos about the Drummertime & Tubbutec here: https://tubbutec.de/drummertime/

Have fun!!!!"

Oberheim Two Voice + Tubbutec MIDI (Sequences)

video upload by Synth Tailor Electronics

"OBERHEIM TWO VOICE + TUBBUTEC MIDI just installed! The @tubbutec uniMatrix Midi kit adds filter control for each SEM independently, and it’s great being able to use a modern midi controller with such an early vintage synth.

Shoutout to Rob Rosen for figuring out the SEM filter controls/making the installation manual for this kit!

The Two Voice/FVS is one of my top 3 favorite vintage synths of all time. This two voice has been fully overhauled and it sounds incredible!
If you have a vintage synthesizer that needs midi or repaired/restored please reach out through our website! www.synthtailorelectronics.com"

CV/gate for EMS Synthi or VCS3 = instant MIDI fun

video upload by analogia pl

"This is one of many videos I've been uploading on IG that feature Papa's CV/gate card - an absolutely indispensable tool for any EMS owner. Add a MIDI-CV converter and you're now in MIDI heaven.

What's happening in this video: CVs and gate are supplied from 2oh2 - Tubbutec modded Roland MC-202. I'm sending CV on channel 1 of 2oh2 to oscillator 1 of the Synthi and another CV channel of the 2oh2 to oscillator 2. Gate comes from channel 1 of the 2oh2.

You can order the CV/gate card here: https://www.portabellabz.be/cvgate.html"

Roland MC-202 with MC-2oh2 Hi-Rez Upgrade

via this Reverb listing

"Excellent condition MC-202 with Tubbutec MC-2oh2 Hi-Rez upgrade. Even adds a cool 8-bit sampler /drum machine that can load 12 of your own samples via MIDI dump.

Professionally installed by Tubbutec authorized installer Borish Electronics, not a cheap job to have done at $500 labor due to complexity involved with tiny CPU removal and replacement + $400 for actual mod kit itself. Overlay can be removed easily if you prefer.

Comes with rare original bag, Roland/Boss power adapter, and manuals (in Japanese)."

Alchemical by MSTRBLSTR

Also on Spotify: https://open.spotify.com/album/68lqZLDB2ip4ZOfEg4SsmB?si=m3ba1VD-SSO_CLr4j7OIMg

"The electricity of live manipulation breathes through every sequence as MSTRBLSTR transmutes the raw essence of the TR-606, MC-202, and TB-303 into a sonic incantation. Alchemical is transformation in motion: analog breakbeats pulse with crackling percussion, acid squelches growl and evolve, and rhythms dissolve and reassemble like matter through fire. The bassline becomes the bedrock of energy, conjured live in real time.

Credits
Released May 29, 2025
Programmed, performed, mixed, and mastered by MSTRBLSTR at Ill Acid
Additional drum programming: Severed Machines (https://severedmachines.com)

Hardware:

Modified Roland TR-606 (Robin Whittle mods)

Din Sync RE-303

MC-202 w/ Tubbutec 2oh2 mod

Mixers: Boss BX-8, Alice 1228, Boss KM-4

FX: Tapco 4400 spring reverb, TC Nova Reverb & Delay, Korg SDD-1000/1200

Compression: BSS DPR-402, DOD SR-866

DAW: Ableton Live

This is the same setup I used on From Deep.

Backstory
I brought my TR-606 to Ramiro at Severed Machines to install a few long-desired mods: switch replacements, a louder BD via resistor change, and Robin Whittle’s Accent Trigger and post-volume individual outs. He left in a few patterns, including a breakbeat variation that really hit me. That inspired the synth parts. Next thing I knew, I was performing and recording the full track.

Recording Notes
I treat mixers as modular routers. For Alchemical, the Alice mixer’s direct outs went straight into my interface, while the Boss BX-8 worked as a submixer for overdrive and tone shaping. I panned certain tracks hard L/R into separate buses, then re-centered them on different mixer channels. I have owned many delays while the Korg units are among my favorites, the TC Nova is often a go-to for synths: it sounds great, has nice filters, tap tempo, and my favorite feature, easily accessible time divisions Protip: a buffered pedal in front helps them sound better. The Nova reverb is also very playable and has a dynamic ducking mode that helps it get out of the way, if that's what I need.

In post, I swapped the TR-606 kick for a TR-808 sample in Ableton - it just gave the track the weight it needed. There’s also a lone TR-808 clap halfway through. Other than that, what you hear is live with only some minor edits and additional processing.

__________________________________________________________________

For TR-606 lovers: I highly recommend Robin Whittle’s mods: https://www.firstpr.com.au/rwi/tr-606/

The Accent Trigger mod alone is worth it - it adds great performance potential. Robin credited the fix to me, but Ramiro deserves most of the credit. Robin's individual outs (post-volume pot) offer superior performance control and gain staging flexibility compared to the more common pre-pot version."
