Transposition has landed

[jcard0na]

Some of you have asked about transposing capabilities of the haxophone.
I'm happy to announce that @petermoz's implementation for transposition just landed in haxo-rs. The gist of it is:

1. Now notemap.json is in concert pitch, no longer in Bb
2. You can pick your default transposition (i.e. for Bb, Eb) by changing one parameter in haxo.service. There is no longer the need for a custom notemap.json to transpose your instrument.
3. You can change transposition in real-time, by using the new transposition commands.

See cardonabits/haxo-rs#27 and cardonabits/haxo-rs#28 for details.

To use this now, you need to compile haxo-rs from the main branch on your haxophone.

Stay musical,

I'm looking to use this function, but I'm a total rookie on the software side. Does the software image on the Quickstart guide include the transport function? If not, do you have any tips on how I could get this to work on my Haxophone?
Thanks!

BTW, you should be able to test the binary before installing by running:

systemctl stop haxo # just to make sure you don't collide with the installed service
cd /media/usb/haxo-rs
cargo run --release

That's faster when doing debugging than having to install the binary every time.

Turns out I was doing the overlay protection wrong. In raspi-config, I needed to turn off overlay protection, reboot the machine, then make the boot drive writable, and reboot the machine.

Then I ran all of your instructions for compiling. After rebooting, I turned all the overlay and write-protection back on.

After that, success! Thanks for the help

I'm going to go blow the minds of the rest of my saxophone section in highschool jazz band lol

The mind-blowing will likely go on Monday morning haha but in the meantime, I hooked the Haxophone up to an OP-1 for a quick little saxophone quartet!

Its incredible how well the transpose function works, I can't wait to mess around with it some more.

Here's what I hacked together last night at like 2 AM 😅

Thanks again for the help getting this setup, I can't wait to see where the Haxophone goes!

I just treid out the transpose mechanism.
Thank you so much for this nice function! It works fine!
