This manual describes how to add midi control to this drum machine using our uniPulse interface.
The machine has been sold under various names including
All 10 instruments can be triggered, most are velocity sensitive.
This manual shows how to install uniPulse in a Korg MiniPops 3 (aka Univox SR-55 and Aria Diamond) and trigger all 9 instruments via midi.
The installation is fairly simple and only requires soldering a few wires and parts into place, as well as drilling a hole for the midi socket.
Here we see the 9 trigger points for the various instruments. These are trigger outputs P1-P9 from uniPulse directly soldered to the trigger points.
In order to power the uniPulse you need to add a few parts, but it is rather simple. The following image shows how we added an additional diode resistor and capacitor in order to get a positive supply voltage for uniPulse. These parts are included in the kit on request. This is a 100uF capacitor, a 1N4148 diode and a 2k resistor. The resistor avoids high voltage spikes, its value is not critical. A 2.2k resistor can also be used.
As you can see the capacitor is connected to the black GND connection with its negative pin, the diode feeds a positive voltage to its positive pin. The resistor is soldered across the capacitor. The brown +V wire from uniPulse is connected to the positive side of the capacitor.
Ground connection (red GND wire from uniPulse) can be connected at the point seen below.
Installing the midi socketInstalling the midi socket is simple. A drill guide is included in the kit. Any location is fine, we chose to install the socket in the cable compartment of the machine. The white marking on the midi connector points inwards on the uniPulse board.
After installing uniPulse, turn on the machine and make sure the LED on the uniPulse is turned on. This means it has power and is running.
Connect midi and use the config tool to upload the following configuration.

Merry Christmas and a happy new year!
We’ll be closed for 2 weeks until the 2nd.
Last day of shipping is this Thursday the 19th. We will of course accept orders after that, but these will be shipped on the 2nd next year.
Please understand that there will only be limited support during our absence, but we will of course be back for you next year.
Have a nice time and enjoy the Holidays !
This is a short manual on how to replace the Minerva mod for Juno-60 with the Juno-66. A few people have asked about this and we finally got the chance to perform the conversion.
The amazing audiowerkstatt tools are now available in the Tubbutec shop and can be purchased in combination with Tubbutec products.
These instructions show how to connect the uniPulse to your MR-10 in order to trigger the instruments via midi.
These informations were sent to Tubbutec by a customer and could not be verified. They work for him and also make sense when looking at the schematics.
Connect uniPulse pins P1 .. P7 as shown in the picture above. Using the configurator, config all outputs as -8V, Rect or Open Rect, velocity link to voltage.
You can trigger the following instruments:
Bassdrum, snare, low tom, high tom, cymbal, hihat and high bongo
Getting power for the uniPulse is not as straight forward. The MR-10 has a strange -9V power supply. We therefore recommend to use an external 12V supply.
Alternatively, you can connect uniPulse as following: (However this has not been tested)
-9V from MR10 —> GND uniPulse
GND from MR10 —> +V uniPulse
In this case all triggers need to be set to +9V (not minus) and the velocity voltage link set to ‘Velocity R’
This is the instruction manual for installing uniPulse in a roland TR-808.
It adds the following features:
When the sync switch is set to OUT, the 808 will output the internal clock via DIN-sync.
When set to IN, the 808 will be clocked via external DIN-sync when it receives a DIN-sync signal, otherwise by midi clock.
You can even use an Y-cable at the input to get a built in midi2din conversion.
Receiving a synthesizer via post and sending it back again sounds very straight forward. However in reality it means a lot of additional work often exceeding the time to do the actual repairs / modifications.
As always we recommend contacting a local tech instead of sending us your synth.
Here is why:
– When receiving a synth it is often not delivered to the door, but needs to be picked up from the post office. This means going by car and takes at least 30min, often more due to long waiting times in the post office. One hour is a typical duration for this task.
– If the synthesizer needs to be re-packaged, this means additional time. Of course we will try to use the package it came in, but sometimes it is nessesary to do so. If you have ever packaged a synthesizer, you will know that 30 min is a rather generous time estimate for this task.
– We can book a pick-up option for shipping the synth, so no additional time here fortunately.
If the synthesizer is sent from outside the EU, customs get involved:
– When receiving the synthesizer via DHL Express, we typically only pay customs (Sometimes we have to pay a small additional fee). Other carriers have large fees for handling import however. TNT for example charges at least 50€ for handling the import. When not shipped via an express carrier, typically we need to handle customs ourselves. This means filling out paperwork driving to the customs office (which is quite far away) waiting in line, eventually paying customs duty and having to drive back again. Three hours is a realistic time for these tasks.
– Finally, when exporting to a country outside the EU, additional fees may apply due to complicated export paperwork. This is true for all shipments with a value greater than 1000€. We use an agent for this and he charges 45€. Please note that if we claimed a lower value, it would not only be illegal, but it would also mean your shipment is not insured properly.
– It is possible to import goods ‘for repairs’ and this way getting back the customs duty paid on import. It means however a substantial amount of additional paperwork, often offsetting the cost of customs duty.
Our new eurorack module Sumtiple is now available. Sumtiple is a high precision adder and active multiple on only 2HP.
