Here is how to add velocity sensitive midi input to a Korg Minipops 120 using the uniPulse.
Audio demo coming soon…
Jacob Korn was kind enough to share his documentation of adding midi to the classic Vermona DRM drum machine using the Tubbutec UniPulse interface.
Why would you use the uniPulse for a machine that already has midi? According to Jacob the DRMs original midi has severe timing issues and with the uniPulse it is much tighter.
This guide shows you how to use the Tubbutec uniPulse interface with a Korg Minipops 7.
The config file for the Korg Minipops 7 is here.
– Full velocity control for all 14 instruments
– Velocity controls guiro pitch
– Midi sync (optional)
The image below shows the trigger points. You can solder the uniPulse trigger outs directly to these points. An exception is the Guiro, which is connected to the uniPulse CV-out with an additional diode.
The SH-1oh1 µTune is a special edition of the Tubbutec SH-1oh1. It has all the features of the SH-1oh1 but also:
The SH-1oh1 µTune special edition is hand assembled and tested in our workshop.
The user manual can be found here: SH-1oh1 µTune user manual (PDF) (Chapter 8 describes µTune features)
The installation manual can be found here: SH-1oh1 µTune installation manual (PDF)
You can order the SH-1oh1 µTune in our shop.

Juno-66 firmware version 1.24 is released. Apart from the seven built in scales, is now possible to upload a four custom scales using a program like Scala. Of course micro tuning is supported and you can have any number of notes per octave. Have a look at the user manual (chapter 10) for details.
In case you missed previous firmware updates, here are a few of the new features since the initial 1.00 release:

The Roland SH-101 while an awesome sounding synthesizer, unfortunately suffers from digital noise on its output. The main source of this noise is the current flowing through its DAC combined with bad grounding. The Tubbutec SH-1oh1 mod reduces the noise floor below that of the original (amongst a lot of other features), but noise is sometimes still an issue especially with bass sounds.
This is the instruction of an easy to perform – and reversible – modification that reduces the noise substantially, by about 10dB.
Polysex, the first Tubbutec product released in 2013 will be discontinued soon. We had made a batch of 50 front panels of which are now 4 left. We are not planning to have another batch of panels produced, so if you were thinking about gifting your Polysix with a Polysex mod, now is your last chance..
We will however continue selling Polysex PCBs for a while.
