Hi there,

I have put together a programmer that can be used for working with DX7/TX7. It was originally designed for Rhodes Chroma, but supporting my TX7 came to my mind immediately after Chroma started working with it. The main idea is to visualize the sound parameters and keep reading all patch / program changes, so that the information on the LCD is always up to date.

Demo of using it with TX7 can seen at??and info about the project at?

I know that some of you might think that this is a promo for my project. But my main motivation is to hear your feedback and suggestions. My long term goal is to make it easier to work with patches on classic but hard-to-program synths and dsps.

Cheers,

Martin

Electra One looks great! ?One question - does it support downloading the patch settings from the synth to set the initial values of the patch? ?I have a DT7 which is awesome but one drawback is it’s hard to accomplish the use case of “slightly tweak an existing patch.”

Okay, a couple of questions.
Am I reading this right, that it's computer control for patch editing for DX7/TX7 devices? If so, how blind accessible is it? Meaning, does it use standard Windows controls to edit, like arrows, tab, home and end, and page up and down? Add spacebar select to that list. Any keyboard shortcuts or accelerators?

Hi Tom,

yes it does. If you connect both MIDI IN and OUT of your DX7 to Electra it will communicate with it to keep in sync.

If DX7 is on the list of connected devices (define in Electra’s preset) Electra will fetch current patch on start up. Same counts for program changes, whenever you change the program in DX7, Electra will catch that info and will fetch the patch. Please see this video:

As it has 360 degree pots, it will not then make any abrupt changes in the sound. It will just start from the point where given parameter value really is. And they are real potentiometers not encoders.

Oops.? I meant to say "Although NRPNs are 14 bit", though actually some CCs (31 of them?) are allowed to be 14 bit too, and that's used on a few synths, like the Moog Minitaur, for example.

So, maybe 14 bit support ought to be considered generally.

As well as MIDI CCs, it would be a good idea to support NRPNs, and maybe RPNS.

I can think of two synths I own that rely heavily on NRPNs, for external control / patch editing - the DSI Mopho Desktop, and the Bass Station II.

On both, CCs only allow you to change a small subset of the parameters.

Although CCs are 14 bit, it's probably acceptable to treat MSB and LSB as two separate 7 bit numbers, if that makes things easier, and it seems fairly common to use an NRPN to just represent a 7 bit value - but it could be either as the MSB or the LSB, depending on the manufacturer, or maybe even the particular model of synth.

Technically NRPN/RPNS are a special case of normal CC messages. So
if CC is supported properly, NRPNs/RPMS are also supported.

Right?
