Synth Controller

Synth Controller

Product update 2019:
From 2019, the Controller has thinner knobs, at the same time the cutouts of the faceplates were enlarged.
Now you simply can throw the faceplates over the knobs while they are still attached.

Synth Controller Overview

The Synth Controller is a highly specialized midicontroller allowing realtime edits on your favourite music synthesizer with 16 knobs. At the moment you dial a knob the Synth Controller sends the appropriate command to your synth which immediately changes it’s sound. Completely independent from software and computers.

The midicontroller will be plugged in between the midi sending device and your synth. It merges incoming midi data with it’s own parameter change commands and forwards both to your synthesizer. Means: you can perfectly fire your synth with midinotes while tweaking it’s sound with the synth controller – realtime.

The 16 dials of the Synth Controller are split in 3 color layers, each knob has printed up to 3 parameters under the knob. By pressing one of the 3 immluminated push buttons you select one of the layers. In consequence you got up tp 48 parameters in direct access.

The Synth Controller also got a built in translator converting incoming ordinary CC (‘Controller Change’) data into the complex Sysex commands. You can remote or automate your parameter changes using Midi-CC data. (Translator only present in editions using SysEx-data for parameter changes).

Synth Controller Features

  • Synthesizer eardware realtime editor
  • High quality and durable parts
  • Cute and tough steelcase Made in Germany
  • Potentiometers for direct access, (no endless encoders)
  • Diode to prevent damage by wrong polarity of PSU
  • Faceplate design suitable to the design of the target synth
  • Highly optimized, native firmware
  • firmware update through Midi-Sysex-Dump
  • Built in ‘CC / Sysex’-translator. Automate your synth with ordinary CC-data. (Only in editions using sysEx-data)
  • Dials with few value changes (e.g. LFO waveform) just send data if changes really happen. No sending of redundant data.
  • Handy ‘turn the pot but dont send data’-feature to prevent parameter jumps
  • ‘Bypass Mode’ letting pass all incoming data unprocessed and locking all pots against unintended changes
  • Learnt midi channel keeps stored on power down
  • Real, printed, 16 paged paper manual included
  • Available as DIY-kit or out-of-the-box

    Frequently Asked Questions

    Does the Synth Controller allow to hold more than on edition at a time? Can i switch between multiple editions somehow? Can the Controller used universally with multiple synths?
    No, the hardware of the Synth Controllers offers room for exactly one edition at a time. It is not an universal controller for multiple synths at the same time.

    Can i dump the 1016r-edition firmware into my Synth Controller in Microwave edition?
    Sure. The hardware of the Synth Controller is compatible with all firmwares. It also does not matter whether it’s the DIY-kit or the assembled version. Btw, if you jump over to ‘Manuals’ you can download PDFs for printout of all faceplates.

    Can i make editions or templates on my own?
    No, we dont offer a tool to make editions on your own.

    How can i dump another edition into the Synth Controller?
    The steps for the firmware update are described in the manual.

    Does the Matrix-Edition allow tweaking all parameters of the Matrix 1000/6 including the modulations matrix?
    No, the Synth Controller just offers the 40 most important parameters, including ‘Unison Detune’ introduced in the Matrix1000 OS Version 1.16. For modulation matrix edits to make sense, the controller would (among others) need a display. Take a look on our Synth Programmer offering convenient access to all parameters , including the mod matrix.

    Does the 81Z edition also work with the Yamaha DX-11 / DX-100?
    Yes, according to customers the 81Z edition works well with the DX11 and also DX100. There might be parameters on the DX-100 which the 81Z does not offer. These wont be supported then.

    No edition for the Yamaha DX-7?
    No, for a reason. FM-Synthesis is so complex – a simple controllerbox with 16 pots would not do the job. A focused editing would not be possible, it would be more kind of gambling. But we already plan to build a special FM midicontroller for the Yamaha FM family.

    Why is there no edition for the Crumar bit 01 / bit 99?
    The bit is a really nice sounding synth but it’s midi capabilities are … well, rudimentary. It does not offer single parameter changes. If you want to change something you have to dump the whole patch into the bit. This would not be a problem as there are quite few parameters. The problem is: the Synth Controller has no idea about all the other parameter’s values if it wants to change one of them. A midicontroller for such tasks needs a bi-directional midi-interface to allow non-destructive edits. That’s the reason why it does not make much sense trying to build an edition for the crumar. Maybe one day there will come an edition for the bigger Synth Programmer which in fact has such a bi-directional midi interface.

    How long will it take to assemble the Synth-Controller DIY kit?
    About 30-60 Minuten – depending on your skils and how much time you take.
