Feature Requests and Feedback / Re: chord / melody relationship
« Last post by mario on October 30, 2017, 11:01:15 PM »
You're right, the melody notes really do stop, and it was unintentional. Recently reworked most of the core (due to variable BPM) and this is a collateral damage. I quite like it, so it will become an option/setting :)

Also, that particular channel plays probably the longest song of them all - it looks like it overruns the receive buffer... thanks for the heads up!

The score editor in the app is currently undergoing major upgrades - there will be more than one keyboard layout, to make it easier for people who play something else than the piano...

Rests and pauses aren't there yet, I remember you suggested it. To make keyboard activity clear and more versatile, there will be a switch to either put text directly or to "play" on it with all the required extra notation put down automatically.

So, perhaps the implementation gap... hope to close it soon in the way that doesn't end up with two smaller gaps :) Thanks again for your great feedback.

Feature Requests and Feedback / Re: Melody / Chord volume

Cool! :) Of course, that is quite simple to do, the hardest thing is to decide where to put the settings so the whole "menu system" stays well organized. It is easy enough to put it into the app but the goal is to have it all achievable with a stand-alone unit in the first place.

There are other things too which should be configurable - e.g. low-pass vs. high-pass mode deserves a separately remembered setting for mic gain, as the usual level that is high enough for low-pass is way too loud for high-pass. Then, separate volume for melody played by filter vs. melody played by sampled sound. Adjustable mixing volumes of delay line - currently it is at 2/3 multiplier but might not be ideal in every case, and who knows maybe mixing the signal back into the loop at 99% will produce interesting results. And this all is just for starters, every new added mode/feature will probably require new group of settings too :D

Playing channel 4121 from Gecho in the normal [stand-alone] manner currently returns a melody line which sounds as though rests have been implemented, to my ear at least; the melody notes occur, they do not inappropriately sustain into the next melody note. I guess I need to check this listening 'dry' - the echo may be confusing me :)

Downloading that channel into the editor to see how this is being done displays periods [the symbol previously used for sustained notes]
Trying to play the channel contents from within the preview facility in the editor appears to result in no activity at the Gecho.

Incidentally, the spacebar on my keyboard appears to insert periods when entering Melody in the app entry window, but spaces in the Edit window.

Am I just falling into an implementation / UI gap, or am I doing something wrong, or?

Feature Requests and Feedback / Melody / Chord volume

Really enjoying the expanding capabilities!
Is there a means for adjusting the volume of melody and chords separately? I didn't find it. If not, is that something which might be implemented?

No worries, it is easy enough to do. Iíll write up the steps and post them in case there are any other Mac users out there who need help.

That's fantastic, happy to hear it worked for you!

I'm afraid you'll need to do it again as a new version went out this evening :D

I was able to flash the firmware using the serial drivers and the python script. Thank you for the help.

That's great. Do you have ST-Link v2 (SWD adapter) too?

There surely is a way to upload firmware with or without it, via USB only - many other devices use the same or compatible architecture, for example modules from Mutable Instruments, ST Demo boards or various Arduino-compatible boards.

Does this guide apply to your system/version? You only need to install the st-util, then download the latest binary from here and flash it.

The alternative route without SWD adapter:

First install drivers, then upload binary using serial bootloader.

"Enabling the Bootloader" step is on Gecho achieved by switching off and pressing reset - you should see LEDs glowing in this pattern.

As not a Mac user, I cannot help you with more exact or verified steps, but hope this points you in the right direction.
