Can I send you my synth for repairs/mod install?

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.

On holiday until the 21st August. Shipping will continue, but support may be slower. In urgent cases please write to Alex(ät)tubbutec(döt)de, shipping related questions to shipping(ät)tubbutec(döt)de

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.

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.
