@salass00

I see. So the "/" comes from the AROS sources or is it something used commonly in the linux/osx sources too?

@densho @salass00
Yeah that seems to be the problem and I see in the Protrekkr manual uses of left"Ctrl" so that rules out using just "Ctrl" for play song.

Would mapping "Play Song" to another key be a stupid move if you take future updates(which may use that key) compability into consideration?

About right CTRL, maybe related to this SDL2

@sinisrus

New version has lots of sound processing included. Few tips for increasing the speed:

Quote:
You can try increasing the PROTREKKR_MAIN_LOOP_DELAY: 20 fps: setenv PROTREKKR_MAIN_LOOP_DELAY 50 SAVE 10 fps: setenv PROTREKKR_MAIN_LOOP_DELAY 100 SAVE Latency setting should be at least 100 ms to get good sound but if it's not enough you can try increasing it.


Quote:
- Linear interpolation can now be selected (beside none or cubic) it's faster than cubic and still gives better results than none.


Disable the dsp effects you don't use. Every track can have reverb, filter, distortion, EQ, compressor, LFO, flanger etc. On low-end machines these eat cpu but on X5000 haven't found the limit yet :)

Some updates:

Fredrik said he could try to take a look at the MIDI code implementation (no promises were made here) but one year after and no updates it seems it's not going to happen.

I'll donate 303 euros via paypal to first who provides OS4 version of Protrekkr with working midi.

NOTE: You don't need any MIDI equipment to test it, you can use Timi (available in the OS4.1FE contrib drawer) . There is also example code and some documentation provided by LyleHaze.

Are you offer to Salas00 that as well? I mean, if you will ask him to made what he was hoping to make for 300 eur, maybe he will do so.

If he does, I'll donate as well. I assume Protrekker's MIDI implementation is quite basic, so it could be doable. (Unfortunately, C++ is out of my league.)

That would be the best option, of course. I offered - but unfortunately didn't get any comment on that.

@Trixie

Nice, I was hoping other donators would join in :)

I think I promised to look at it as well. I was busy and then I forgot it. I did put something together already. I didn't have time to see how the tracker itself works or how it all goes together.

@Tomppeli

Good to hear there is some progress with this topic! Let me know if you need help with testing.

Small update;

Tomppeli provided some code but unfortunately, it's no use as it is. There are two files modified, RtMidi.cpp and RtMidi_Amiga.cpp. There are also couple of issues in this code that should be fixed. I haven't received any more info regarding this but maybe Tomppeli can explain here, if needed.

You can check the files here.

Fredrik has also some preliminary midi code available(?) and here some comments from him:

"It is quite long since I looked into implementing a CAMD interface for ProTrekkr but a possible problem I remember seeing with it that isn't addressed currently is that the RtMidi class is not always called from the main thread or the thread that created it which likely will cause problems as CAMD needs an allocated signal. A possible solution to this would be to create a separate thread for all of the CAMD stuff and then do messaging to/from it."

It's been since 2018 with no significant progress with this project and sadly little interest by contributors - but I guess that's common problem with every amiga project nowadays.

Good suggestions on how to proceed are more than welcome. The offered "bounty" us still valid and others can join in.
