ZynZilla - able to get it to appear, but not generate sound

Help, Support & Bugs
#1

OK, I read somewhere, on some post here in the forum, that adjusting the API value would quite often resuscitate ‘dead’ plugins. So I did - figured out how to update the manifest.xml, from 2.0 to 6.0. Now the ZynZilla plugin appears! Neato-beato.

But, Zynzilla does not produce any sound, nor does it generate any waveforms.

While I do not code in any language, I was able to figure out where to find the issue is, by viewing the Terminal feedback from the plugin. Here’s the message I got:

*** std::logic_error: ‘invalid sample index ‘0’. valid values are (1 to 1).’
*** stack traceback:
*** [C]: in function ‘insert_sample_at’
*** main.lua:537: in function ‘generate’
*** ./gui.lua:861: in function <./gui.lua:860>

Would anybody have any idea what I could copy/paste into the plugin, so we could all get this neat sound generator back?

#4

This is where it seems to be stemming from, but the only thing that looks suspicious to me, because I don’t code is the portion that says:

(int_sample_index), int_note-1, {0,119}, {0,127})

in particular: int_note-1

if current_mapping == nil then
current_mapping = instrument:insert_sample_mapping(LAYER_NOTE_ON,
(int_sample_index), int_note-1, {0,119}, {0,127})
else
current_mapping.base_note = int_note - 1
current_mapping.note_range = {0,119}
current_mapping.velocity_range = {0,127}
end

What might it be? The only thing I can figure is that maybe it’s a spacing issue. I tried adjusting that, but nothing changed.

I’m basically just grasping at straws :smiley:

#6

Did those changes

if current_mapping == nil then
current_mapping = instrument:insert_sample_mapping(LAYER_NOTE_ON,
(int_sample_index), int_note, {1,120}, {1,128})
else
current_mapping.base_note = int_note
current_mapping.note_range = {1,120}
current_mapping.velocity_range = {1,128}
end

Then got the same message.

*** std::logic_error: ‘invalid sample index ‘0’. valid values are (1 to 1).’
*** stack traceback:
*** [C]: in function ‘insert_sample_at’
*** main.lua:537: in function ‘generate’
*** ./gui.lua:861: in function <./gui.lua:860>

So, I’m wondering if the “0” in this bit (line 537) is the issue

if(int_samples == 0) then
sample_new = instrument:insert_sample_at(int_sample_index)
else
sample_new = renoise.song().selected_sample
end

buffer_new = sample_new.sample_buffer

if int_frames == 0 then
int_frames = SAMPLE_FREQUENCY / note_to_frequency(int_note)
end

I changed both zeros to ones, no dice. Maybe this plugin’s just dead :slight_smile:
