HiRes is an upgrade for the ModyPoly which adds high pitch resolution, microtuning and portamento. It works for Polysix and Mono/Poly
Here you will find information on how to add single outputs to your beloved Minipops-120.
This mod is compatible to midi added with the uniPulse. An uniPulse installation manual for Korg Minipops 120 is here.
Attached is a picture (extracted from the service manual) of the circuitboard and the points/parts you have to desolder to add single outputs. The HighHats and Cymbal share the same output, so you will get 7 single outputs for Bassdrum, Snaredrum, Claves, High Conga, Low Conga, Bongo and Highat/Cymbal.
This is a quick manual how to install the ModyPoly in an Korg Poly-61M. The existing midi sockets are used, so no new holes have to be drilled. Incomming midi messages are passed to both the original midi implementation and the ModyPoly. Outgoing midi messages will be from ModyPoly only.
The files include front panel mechanical drawings and print data, schematics and PCB layout, the mechanical stencil design and manuals.

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:
- New school chord memory modes
- Optional auto portamento in MONO B mode
- Three voice mode
- Looping mode, delay and polarity for ADSR

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.
Michael Kukat did an amazing job servicing a Juno-6 and installing the Juno-66 mod. With the flawless soldering and carefully placed components the pictures get an aesthetic touch. These are worth a look at – even if you don’t plan to install the Juno-66.
