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

Installation

If you want to Install the UniPulse into the TR606 there is a little extension board needed also you will need a “special” UniPulse version as there are some little modification to the circuit board needed. Also There is a red cable already soldered to the Unipulse. This cable needs to be soldered to the location marked in the picture underneath.

You can order it in the shop as a kit.

Here you can see the assembled extension board for the TR606.

Start with soldering some extra cables to the GND pad and to the pads underneath the diodes (T1 to T7). Note that the order is not important here. so you dont have to connect the first pad from the additional board to T1. Connect the GND cable to GND on the TR606. Solder the D3 cable from the UniPulse to the CM pad.

It should look something like this:

Now you can start and solder all the cables to your beloved 606. Attached you can see the trigger points coming from the UniPulse (marked P1 to P13 and with a circle) and the connection points from the extension board (marked with a turqouise rectangle). On this picture you can see the bottomside of the circuitboards from the TR606. So it is the side without any components on it.

Solder the cables to the pads that are circled/rectangled corresponding to either the UniPulse cable or the cables coming from the extension board.GND and the two power connections for the UniPulse are also marked. The extra 15V cable coming from the Unipulse needs to be connected where shown. The +5V pad on the Unipulse  needs to be connected to 5V on the 606, marked with “To +5V” in the picture above.

You have 3 options for where to put the MIDI socket:

1) the easiest would be to just put the MIDI socket coming from the UniPulse into the battery compartment.

2) you can drill a hole for the MIDI socket. The benefit of this would be, that you now have a MIDI to DIN-Sync converter build in.

3)You can also use the existing DIN socket on the 606. You will have to desolder R34 (it is an 1MegaOhm Resistor) and you have to cut two traces and jumper one connection. Now you need to cut the red and black cable from the MIDI-socket provided with the kit and solder the cables to the marked points in the picture. You can see all the connections and where to cut in the picture above and the picture at the bottom. If you use an Y-Cable you still have DIN-Sync available. But you will loose the Fill In and Tap option as on the original configuration.

If you wish to sync your 606 to MIDI you will need to solder a 47k resistor between D1 from the UniPulse and the marked point in the picture below. Same goes for D2.
This will allow you to sync your 606 via midi, when the switch is set to the ‘IN’ position.

Hihat decay control

With the CV out from the UniPulse you can controll the decay of the open HiHat. Therefore you need to solder the CV out cable from the UniPulse to a 10k Resistor and the resistor to the marked point on the 606-PDF. You can also see where we cut the connection and jumpered for using the DIN input as MIDI input. Look at the following picture:

We placed the additional board and the UniPulse each inside a little plastic bag and then put them between the mainboard and the switchboard. This way you can still use the battery compartment like before, and even run the TR-606 and UniPulse with batteries!

Configuration

With the uniPulse configurator use this file (right click, save as) and upload it to your uniPulse.

  1. Hi Tobias, hi Alex,
    I like to say, thank you for your very kind support for my bitchy TR606 (you know, each one is like no other)!
    Now everything works like it should, plus I got these extra sound possibilities with the latest update, great!!!
    Best Carsten

  2. hello,

    I’m very bad with midi, but could I control my 606 with my Electribe with that?
    thanks,

    Pierre
