General Discussion / Re: MIDI overview for Gecho Loopsynth?
« Last post by mario on October 25, 2020, 11:01:42 AM »
Hi Michel, happy to hear you are enjoying the loopsynth!

I've only tested it with Arturia Keystep, which transmits on CC1. And it is usually tied to the most interesting parameter / the one effect of which is most prominent in the sound - so you're right it's amount of voices in granular, and the pitch bend control is linked to de-tune.

Is there an official MIDI specification somewhere? I couldn't find it anywhere, but maybe I overlooked something?
No I haven't got to do that yet - thanks for reminding, I need to update channel list with more details about MIDI controls where it was recently added.

I like the sensors, but I think it would be awesome to be able to use MIDI CC to control the sensor effects.

The other cc numbers are ignored, but it would be easy to link them to the other 3 sensors. And in Clouds engine they could directly control the 8 most useful out of the 10 parameters available.

And maybe use sensors in conjunction with CC, so they add up...
That is certainly possible too.

What controller do you use - does it have more wheels or does it rather allow to select what the one or two wheels do?

Cheers,
Mario

General Discussion / MIDI overview for Gecho Loopsynth?
« Last post by michelrandahl on October 22, 2020, 10:46:19 AM »
I just received my Gecho Loopsynth two days ago, and I am very pleased with it so far and have already spend lots of hours in its company, especially with the looper, the granular effect thingie and the clouds reverb. Managing the clipping and sound levels can be a bit challenging at times, but a part of my also enjoys these 'untamed' sounds...

While playing around on my MIDI keyboard, I quickly found out that some channels can react to CC and pitch.
My mod-wheel seems to use CC 1, and I noticed that this modifies something in the granular effect (maybe it's the amount of voices?). On other channels I noticed that the pitch wheel affects the amount of reverb.
After experiencing this I tried out CC 0 to 8, to see if any channels would react to other CC's, -but it doesn't seem so, and I didn't want to try out all 128 CC's...

Programming Questions / Re: JTAG or USB for programming
« Last post by mario on September 21, 2020, 01:27:01 PM »
Hi and welcome! :)

The easiest way is to connect via USB, that's what I use when developing the firmware. And it is supported by official environment.

But indeed JTAG offers more comfortable debugging, if you want to use it you'd need to hi-jack pins that are currently used for SD card:

Maybe there could be an adapter in the form of micro SD card to wire them out.
If reset signal is needed, it can be taken from the pad on top right of the board - top pad is RST, bottom is GND:

Programming Questions / JTAG or USB for programming
« Last post by FondsofFall on September 18, 2020, 08:47:50 PM »
Hello everyone,

  Just discovered that the processor chip is based on ESP32, will it needs to connect JTAG or micro USB for writing codes?

Feature Requests and Feedback / Re: tempo of the chord progression
« Last post by jluc on July 12, 2020, 12:06:50 PM »
In fact, I already find the channels terribly musical. The little extra to go beyond the experimental (necessary anyway to surprise yourself and create creative accidents, this is also the strength of this project, I believe) would be to be able to save a current state and recall it (by midi for example), as well as the possibility of making a mapping of a succession of channels with their presets, for live use. I think we has already spoken more or less in a previous post.
Today, I mainly use it to create material and until now, I have managed to produce sounds in this way with MAX MSP. Doing it now without turning on the computer and without a screen adds a dimension I think.
this tool is unique and I thank you for your work ! :)

Happy to hear that! 8) It's a work in progress - still has some way to go to be more useful in music making, I guess.

Thank you for supporting the project!

ok thank you for your answer. I thought however that I had reviewed the modifiable parameters. fantastic ! this box is definitely to my liking !

Hi Jean-Luc, adjusting tempo is possible since the first version, check in the settings leaflet.

The soundscapes default sample can be replaced with the last recorded track by pressing SET+RST but not fully finished with all options. Hope it's at least good for some experimenting.

hi mario

If for the future update it will be possible to change the soundscape ( I can't wait! ;) ), maybe it would be interesting to be able to also change the speed of execution of the chord progression (tempo) ?
regards
