If this is still being worked on, id love the ability to audit drum samples, so the tool can tell me what kits are being use and which are not, so I can decide which of the stock kits I can ditch to replace with my own easily.

In fact, I think that lsdj asks for a confirmation if we try to manually override the waves.
The field is "wave_synth_overwrite_lock".
I though that if it on, lsdj with use hand drawn waves. And synth settings won't be synchronuized, that's normal.
If it is off, lsdj will use waves generated in the synth screen.

I am wrong?

I think it would be great to have it read/write, to 'upload' custom samples without patching the kits in the ROM

Ah, yeah the docs are a bit misleading here. You can change the individual waves to your heart's content, but the other synth settings (volume, cutoff, phase, etc) won't stay synchronized with the wave.

In any event, the waves are just 32 hex nibbles, and can be edited just like an array of numbers.

Hey Alexras, nice work! I haven't spent too much time with this yet, but I'm excited that you seem to hhave made a way to import/export instruments. I didn't see any wavetable data in the .lsdinst files. Is there a way to include those in the instruments?

Edit, nm I figured it out, dur. So you can't write the wave data to a sav file though? Is that correct? You say in the docs, "Note that waves in pylsdj are read-only, since updating parameters will invalidate the raw waves." Sorry just trying to understand if there are any limitations.

An update:

pylsdj 2.3.0 should resolve a lot of the speed problems that have plagued the library in the past. I added in a bunch of lazy loading that wasn't there before, and it appears to have sped things up substantially.

I won't spam this thread with future update announcements; if you'd like to stay current with pylsdj's development, here's an RSS feed:

Yeah I tried to use construct as well, but I find bread is better (even if slower)

I'll try to update to 2.0, I still have some tests failing in python3, but there is progress.

Yeah, .sav loading being slow is a known problem. For what it's worth, it's a lot faster JITed (running through pypy, for example), but that's probably more of a consequence of bread being a bit too clever with class internals for its own good. I've considered switching the backend to construct, but perfect is the enemy of done.

If you're not working off 2.0, you should be. I did a pretty big refactor of instrument internals last night that I'm still writing tests for / debugging.

Alexras, we have forked pylsdj and bread to improve compat with python3
I have done some profiling as well, because loading a .sav is VERY slow!

But otherwise, bread is really great, thx!

Let's continue on github ;-)

Nice! This is exactly the sort of thing I'd hoped people would write.

Hello!

Using Alexras wonderful libraries, we (at http://TheOtherDays.net) made a commandline utility.
With it you can:
- print information about a .sav or a .lsdsng file
- split a .sav file into several .lsdsng files
- join several .lsdsng files into a .sav

It can be used like lsdjmanager, but in a more automated way.

Please use it carefully and keep backups because it is still new code!

It should work with python2 or python3

Please use the github page here:
https://github.com/TheOtherDays/todmisc-songops
to report issues.

Just found out, the LSDj Patcher .Jar file works on Mac - if that might save you more time.

Nice, hope it goes well!

Will it be able to to possibly manage custom kits too? Really tired of having to use others computers and/or get over the official windows signature from more update versions of windows when something like this for mac should also be available.

Very cool. Nice job.

really excited to see how LSMC turns out- some of the limitations of LSDManager seem to be remedied by what you've implemented in pylsdj and having a proper GUI for it sounds great.
