Individual Outputs for Korg Mini Pops 7

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.
schematic-instruments_percussionboard_rueckseite_percussionBase 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.
schematic-instruments_base_hiha_cym

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!)

ModyPoly for Poly-61M

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.

Korg MiniPops 120 uniPulse installation

Here is how to add velocity sensitive midi input to a Korg Minipops 120 using the uniPulse.

Check Minipops-120 Single Outputs for information on how to add single outputs.

MiniPops 120P – the portable version of the MiniPops 120

There is a portable version of the MiniPops 120. While electronically identical to the normal version there are mechanical differences. Hence you`ll find details on how to install Unipulse in this PDF:

CR-5000 / CR-8000 trigger points for uniPulse

This is how to install the uniPulse in a CR-5000 or CR-8000.

 

Update: User ‘a.d.a.m.baby’ on MuffWiggler found some great additions to this manual.

Here are the schematics and pictures with trigger points. Points in blue must be triggered with a negative voltage, points in red with a positive one. You can connect the uniPulse trigger outputs directly to these points. Use the configuration program to program the behaviour and polarity of the trigger outputs. Trigger points can be found on the bottom of this post.

Here is the schematic with the trigger points.

On the next picture you will see the whole CR-8000 voiceboard with the cables connected to each trigger point. Open the picture (download it) and zoom in to see where exactly the trigger points are. P9 is not used, please ignore!
If you want to trigger the Accent, solder the cable from D3 to a 1k Resistor and a Diode (1N4148 or similar; Polarity like shown in the picture) and the other end of the diode to the trigger point. In the config file provided accent is triggered via a midi note. If you prefer accent to be triggered if velocity is at 127, you can configure D3 as ‘Accent’ in the config tool.

They are labeled P1 to P16 corresponding to the uniPulse trigger outputs and colors.

Midi sync CR-5000

In order to add midi sync to the 5000 you need to cut the two traces coming from IC15 as shown in the schematics below. You then add a two pole switch and connect it to two digital outs of the uniPulse. Configure the outputs as clock and start/stop. You can now use the switch to change between internal and midi clock.

There is another method to install Midi Sync on a CR-5000, as pointed out by a user. We don´t know if this is true for all CR-5000s, but the machine of the user has jumper wires installed which can easily be desoldered and the switch can be installed in their locations. The solder points closest to the CPU go to the middle pins of the switch.

The user also pointed out that the Sync Gate (the D1 line from Unipulse) needs to be inverted. We don´t have a CR-5000 at hand, so we couldn´t check this. You can just try that if you´re having trouble when using the provided config file. Just invert the signal in the Tubbutec Unipulse Configurator software and upload it to Unipulse.

Midi sync CR-8000

For the CR-8000 sync is very easy to install as it has a din-sync input. Just connect two digital outs of the uniPulse to the DIN-SYNC start and clock lines and configure the outputs with the configuration program.
You don’t even have to drill a hole for the midi socket – you can use the existing dinsync socket without losing its functionality because pins 4 and 5 are not used.

MIDI and DIN Sync

Solder a 47k Resistor between D1 and the cable running to the DIN-Connector, do the same for D2. (if you put the uniPulse to the same position we did, the cables from the uniPulse may not be long enough, thats why the cables have a different color on the DIN-socket) See attached pictures.

You need to cut the wires from the MIDI-connector provided with uniPulse. Solder the cables the same way they were to the DIN-Connector of the CR-8000. See again the picture above.

Now you can put the uniPulse in place. Use a distance holder screw. You can also find a different place to put the uniPulse if you like.

Finally you only need to upload the CR-8000 / CR-5000 config file to the uniPulse and you are ready to rock!

Midi for Korg Minipops 7 (uniPulse installation)

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.
