Hi Brian,

I'm currently working on a fork of Specimen called Petri-Foo, so I'm fairly familiar with how Specimen works, although Petri-Foo is somewhat altered by now.

The main differences between the two are that Petri-Foo has more configurable modulation possibilities (now with selectable MIDI controllers too) which might or might not be better for live performance. It also loads up with a default saw wave patch (useful for new users), can load raw audio data, all deprecated GTK code has been updated (file selector being one example) and the waveform display now uses Cairo and has other enhancements for navigating between the different marks in the waveform (ie loop points etc). The xml formatting for the bank files has also drammatically changed.

Petri-Foo is hosted on sourceforge [ http://petri-foo.sourceforge.net/ ] and github [ http://github.com/jwm-art-net/Petri-Foo ] but docs are rather sparse so check petri-foo mailing list archives for detail.

Regarding file size, both Specimen and Petri-Foo load the entire file into memory. However Petri-foo won't load files containing more frames than can be represented in 'signed int'. I don't remember what Specimen does here. The other issue with file size is the waveform display zooming is dependant on file size, so you can't zoom in to gain sample point accuracy (when making loop points for example) with very long files. Both Specimen and Petri-Foo have this problem, and the cairo code for petri-foo still needs some work - it tries to be a bit prettier but pays the price in performance (except with regard to window-damage where it does the right thing :-).

8-note polyphony is an arbitrary limit imposed at compile time. That number can be as large or small as desired.

Edit the file src/patch.h and change the value PATCH_VOICE_COUNT enumerates to.

HTH, Cheers, James. _______________________________________________ Specimen mailing list [email protected] http://zhevny.com/mailman/listinfo/specimen
