DxFM Data

[daltronbeats]

Great work on the firmware! any hints on the DxFM implementation? what is the data its expecting? sysex over MIDI? an audio playback / tape thing?

or have i missed something and I need to add an SD card?
Thanks again!

@daltronbeats,

It is actually "work in progress". Parameter control, polyphony, and some documentation is still todo...

Patch uploading is also working with the Plaits-Editor.

Feedback is welcome.

thanks! how long should the 'loading patch.' screen take? I've tried with a single patch and a full bank with varying gain but it seems to always hang on this screen. if i turn an encoder the module reboots and no patches are loaded.
Thanks again for your great work on this

Hi @daltronbeats,

I have updated the webflasher just now.
Now it is possible to load "optional" engines like TR707/TR909, that are sample based and require a lot of flash memory.
You can also load the DX7 patches via WebFlasher.

Check out this website for DX7 sysex files: http://dxsysex.com/SYSEX_DX7/V/dx7-sysex-V.php

I have used vrc-1003_percussion sysex so far without any issues (also upload via audio)

Actually, the popup "loading patch..." comes after everything has been successfully transferred. Can't explain what's happening - could you please try to load the SYSEX with the WebFlasher, and report back to me if it works via audio afterwards?

I was able to load the dx7 factory bank using the WebFlasher. 32 patches selectable and playable via the ui. the Pitch scaling is wrong though, on both Midi and CV in...
still great for percussion stuff, cheers! Audio update completes successfully now every time after an initial webflasher update

(I was also just about to ask for hold to octave shift and its already there!! nice work! any chance you could add a flag to reverse the behaviour? eg always octave shift, always fine control / Hold for semitone and coarse)

HI @daltronbeats
thanks for the Hint - i have fixed the wrong pitch scaling in the latest version.

(Experimenting with stereo and the rate parameter at the moment, Polyphonic Mode is also still on todo.)

Regarding "octave shift" while holding the encoder - I don't really understand the advantage - do you mean in general or specifically for DxFM Engine. If general, feel free to create a new issue.

Awesome.
Since you mention Plaits - Now that the source for the new plaits models/engines have been released, I hope we will see more of them in Squares&Circles ?
