I have an Analogue Solutions Fusebox synth. The one thing that the manual doesn't cover is what the CC55 output does. It's a 3.5mm output jack on the MIDI CV section of the synth. I've tried searching the internet to no avail. The other output jacks on the synth in the MIDI CV section are pretty straightforward and easy to use and understand (pitch, accent, M. clock, gate, velocity). But then there's the cc55.

Any help clearing this up would be most appreciated.

Thank you in advance.

Basically, I don't know.

In midi, anything CCxx usually means a Control Change, i.e. one of the controllers.

However, CC55 is not a usual controller in it's own right. There are a block of 'Continuous Controllers' which are 'undefined' as far as midi is concerned, which usually means that they are available for use by specific devices as defined by said specific device. However, 55 is for the least significant part of CC23, and therefore would be unlikely to be used apart from CC23.

However, as these controllers are 'undefined', there may be certain devices that do use them for their own purposes. If, as you say, these connectors are outputs, there may be something that can use a CC55 input (but if so, what about CC23 ??). Maybe something else in the Analogue Solutions range can make use of this?

I'd suggest that you don't worry about it unless you have something that can use it?

CC55 is a general purpose controller. My guess is that it is just set up so that you you send control value on CC55, it will control the output voltage of the jack for whatever you want to use the jack for. Of course what ever you have connected to the jack would need to take that voltage and convert it to whatever function the device that you connect provides. As an example an analog expression pedal typically puts out a voltage which is variable depending on the position of the pedal. A keyboard would recognize this input as a change of volume depending on the input voltage. It appears the manufacturer arbitrarily decided which CC# to use for this particular output jack.

PS. Maybe my example was not a good one. I think in case of expression pedal, the instrument actually puts out the voltage and the pedal just changes the resistance applied. Be careful you know what you are doing before applying and output voltage to anything!

Oooh, I think I should be a bit pedantic here, I'm sure for the benefit of others.

Midi has nothing to do with control voltages. So going back to the OP, I'm not sure that 'MIDI CV' is all about, and I should have asked that question at the start. Midi is just numbers, numeric data, which may well be converted into control voltages by the receiving hardware. The precise conversion will be dependant of various midi settings, so the +127 to -128 in one instance will not necessarily have the same degree of change as in another instance. So, we should NOT mention CV in the same breath as midi. IF the connector being discussed is actually relating to a Midi Controller, then is should be midi data, and NOT CV (which is NOT midi).

We still need forther comment/input from OP
