After installing the UniPulse in your Korg Mini Pops 7 you can also add individual outputs for each instrument.

Picture by Telharmoneum, Install by Simon Ayton

Fifteen different outputs are available, but of course you can only install some of them – for example 12 like in the picture above.

PRE IN Bus

Many of the instruments are connected to the “PRE IN Bus” which is marked red in the schematic. To gain access to each instrument connected to the “PRE IN Bus”, you have to desolder one pin of each resistor connected to it. Leave the other resistor pins connected.
It is not too easy to find the resistors on the board itself so numbered the spots where you have to desolder the pins.

Pre-in connections – overview

Pre-in connections 1 – 7

Pre-in connections 8 and 9

1 – 47k (Rim Shot)
2 – 33k (Claves)
3 – 82k (LB)
4 – 330k (SB)
5 – 100k (Conga)
6 – 82k (CB)
7 – 68k (CB)
8 – 680k (SD1)
9 – 470k (SD2)

Now solder the jack’s signal pins to the resistor pins.We used switched jacks. This way the instruments will be connected internally when nothing is plugged in.

Note that the 68k and the 82k of the cowbell have to be soldered together, unless you want to have both parts of the CB sound available independently.

Percussion

However not all instruments are connected to PRE IN.
The following instruments just need a direct connection from the board to the sockets: TAM, GUI and QUI. The solder points are marked below.
Base Drum, High Hat, Cymbals

Originally the base drum, high hat, cymball and the percussion instruments are mixed together. To separate the instruments you again have to desolder several resistor pins as marked in the following pictures. The spots where the cuircuit is opened are marked by two black lines. Once again you have to use switched jacks to close the circuit as long as no male jacks are inserted.

1 – 47k (BD)
2 – 330k (HH)
3 – 47k (CY)

Solder wires from the desoldered resistor pins to the socket’s tips and from the socket’s switch contact back to where the resistors were connected originally (marked in the picture above).

Ground

All output sockets need a ground connection. Any point labelled GND on the board will do.

The final result could look like this (image by Telharmoneum, thank you very much!)

We are currently producing a new batch of ModyPoly and Juno-66.
You can pre order now, we will ship as soon as possible.
Will most likely ship not later then mid-May

Currently preparing for Superbooth 2017, hope to see you there!

We are at booth 0305 on the second floor.

The SH-1oh1 µTune is a special edition of the Tubbutec SH-1oh1. It has all the features of the SH-1oh1 but also:

• Microtuning with high resolution
• Upload up to 31 custom scales via midi sysex. For example using Scala.
• Switch scales live
• Includes a scale editor! For each key you can set base note, coarse and fine pitch via midi CC. Save your custom scale when satisfied.
• Export scales via midi-sysex, or send them to other synths
• Custom tuning available on CV-out (5 octaves only)

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.

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.

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.

Happy to announce, that ModyPoly, Juno-66 and SH-1oh1 are back in stock. Pre-orders will be shipped today.

Tubbutec will be at Superbooth16 (March 31st – April 2nd in Berlin)
Our booth will be BL260. Looking forward to see you there !

A new version of the Tubbutec Firmware Updater program is now available. It has been completely rewritten and is now supported on Windows and OSX.
In case of the SH-1oh1 mod, you can now also check the version of the installed firmware.
