Midi for Korg Minipops 7 (uniPulse installation)

Posted on by

This guide shows you how to use the Tubbutec uniPulse interface with a Korg Minipops 7. You can also add outputs for each instrument.

The config file for the Korg Minipops 7 is here.

Features:

– Full velocity control for all 14 instruments
– Velocity controls guiro pitch
– Midi sync (optional)

Guiro pitch is controlled by midi velocity. If you want a fixed pitch, adjust CV-voltage until the desired pitch is reached.

These are the midi notes to trigger the instruments when using our config file. You can of course change these notes using the uniPulse configurator.

  • Note 64: Conga
  • Note 60: SB
  • Note 61: LB
  • Note 75: CL
  • Note 37: RS
  • Note 36: BD
  • Note 82: QUI
  • Note 54: TAM
  • Note 38: SD1
  • Note 40: SD2
  • Note 42: HH
  • Note 49: CY1
  • Note 51:CY2
  • Note 56: CB
  • Note 74: Guiro, velocity controls pich

Trigger points:

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.

SH-101 noise reduction mod

Posted on by

noisy

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.

Update: We added an additional, also very simple procedure to reduce noise further. Is is also a simple addition with a lot of beneficial impact on noise performance. See section “Filter cap for 5V supply” below.

Increased filter range for Juno-66

Due to popular demand there is now a hardware update for the Juno-66. It increases the range of the filter control, which also allows larger amounts for the additional filter ADSR, Tri-LFO and SH/LFO. The range is increased by a factor of three.

We now ship the Juno-66 with this modification, it is however relatively simple to perform and can be done by a skilled solderer and any synth tech. This is how to do it.
