CR-78 midi with uniPulse
Features
Fully velocity sensitive drum triggers
Midi Clock sync
Install
So far we have not had the chance to have a CR-78 in our workshop. So the following install instructions are based on the schematics and are not verified by us.
Below you can see the trigger points we found. There are usually two different possibilities, (red and blue). Both will likely work, but you may want to try them both. The Guiro (green circle) is different from the other triggers and is worth exploring. It might be possible to connect this to CV-out of uniPulse to control Guiro pitch.
TR606 UniPulse Installation

uniPulse TR-606 features
- Full velocity control of all 7 voices
- Six (6!) additional sounds (An 808ish deep clicky bassdrum and a higher pitched one, Only Snare Noise, Only Tom Noise, Each half of Cymbal (the hitting sound and the decaying sound))
- Midi clock input. Clock is also sent to external din-sync devices.
- Midi controlled Open hihat decay
- Midi controlled hihat and cymbal length
- You can install an additional midi socket, or use the existing DIN-Sync socket
Hammond AutoVari 64 midi with uniPulse
These are the installation instructions for uniPulse on a Hammon Auto Vari 64.
This has not been tested and is only an educated guess based on the schematics.
Installation is very easy. You need to solder a few wires to the voice board. Connections are shown in the image below. Connect uniPulse’s V- to GND, V+ to +25V and the rest to the pulse outputs P1. The ‘sandblock’ sound can be controlled via the uniPulse CV output in ‘gate’ mode by connecting it with an additional diode.
You need to configure the triggers to be +13V, Open rect, voltage linked to velocity using the configurator.
And you should be good to go!
ModyPoly: Control Polysix resonance
Disclaimer: While this has been tested and found to be working well,
it is not an official ModyPoly feature (at least not yet).
For this to happen we would first like to test this in more Polysixs
to see if it always works as intended.
So if you find this is not working properly, tell us, but don’t blame ModPoly.
Thanks
The following manual describes how to use the 3rd CV output of ModyPoly (brown wire) to control the Polyisx resonance. You will need at least firmware version 1.57 for this to work. Lower firmware versions will have an inverted response with full resonance at startup.

Juno-66, ModyPoly, SH-1oh1 midi output configuration
Keywords:
Double midi, phasing, as-played, as-sounds, channels, loop
Tubbutec synth upgrades have two midi output channels: An as-sounds channel and a as-played channel.
While this is a very useful feature, and well documented in the user manuals, many people seem to be confused by this and we had to answer “bug reports” way to many times.
So here is an explanation of some common issues:

Rhythm Ace FR6 uniPulse install
This manual describes how to add velocity sensitive midi to the Rhythm Ace FR6 using uniPulse.
Picture via Matrixsynth
This was not tested, the manual is only based on the schematics available. If you have installed this, please be so kind and send us pictures.
Configuration file is here. (Right click, save-as)
Trigger
The picture below shows the trigger point locations. Just solder uniPulse wires P1 – P8 to these points.
uniPulse power
Solder unipulse wire V+ to the V+ point shown in the picture below. Solder uniPulse GND to the V- point.
Clock and sync
It is not impossible to also sync the FR6 to midi clock. It is however rather complicated and involves quite a few extra parts. If you are interested please write us and we will provide instructions.
Rhythm Ace FR-1 uniPulse install
This manual shows how to connect uniPulse to the Ace Tone Rhythm Ace FR-1. It is possible to control all 10 drum voices via midi and they are velocity sensitive.
It is even possible to control the Brush sound in a velocity sensitive way.
Trigger
Here you can see the voice board with the connections of uniPulse triggers P1-P10. The brush control needs a general purpose PNP transistor such as BC557 and a 56k resistor. Connect them them just the way it shown in the picture.
Maestro Rhythm King uniPulse install
Not much info here, this is untested. Here you can see the schematic and we marked uniPulse trigger points of all voices.
In the upper right corner you can also see the +12V power supply for uniPulse.
Here is a picture of the voice board. If you have more info, please let us know
Rhythm Ace FR2 uniPulse install
This manual describes how to install uniPulse in the Rhythm Ace FR2L
This is based on the schematics and has not been tested yet. Please let us know if you have installed it. Bonus points if you send us a video of the drum machine in action 🙂

uniPulse power
In order to power the uniPulse, you need to install a few additonal components. Due to the high voltage after the transformer, an additional 15V regulator must be used (7815). The capacitors should have a voltage rating of at least 35V, more is ok. Connect the uniPulse V+ and V- wires as shown in the picture.
Trigger
Trigger are very straight forward. Most triggers are soldered to the legs of diodes on the voice boards. Cymbal and Maracas triggers are simply connected to the solder points on the voice boards. It is also possible to control the Brush (B), but without testing it is hard to tell exactly how. This will be updated as soon as this information is available.
Clock sync
As always syncing the drum machine to the midi clock is optional and requires additional circuitry.
A level shifter is needed for the start/stop signal. Two pole switch (included in the kit) is used to switch between internal clock and midi clock. In order to access points A and B, desolder one leg of R12. A is connected to the resistor, B is connected to the board where the resistor was connected originally.
Point C can be directly connected to the Start/Stop switch.
