Sorry for new topic but seems best to have a single place to discus the yomo2g2 web app.

The app has had some html tidying and bug fixes recently.

Very sorry to anyone who may have tried the midi function. A mysterious bug was causing some notes to disappear. Turns out the code was fine but I made a patching error. Accidentally connected the clock to the reset on one of the sequencers in bank C. It's not the first time hard to track bugs turned out to be errors in the underlying template patch.

My plans to chain the samples in adjacent variations have come unstuck temporarily due to what seems like a 70ms minimum delay between sending a CC70 and the variation actually changing. I'm not sure if I can solve this with a better control patch.
Plan B would be to split the patch into two slots (VA->SlotC, FX->SlotD) and have the PC occur while the other half is playing. Will need to do more testing.

Made a better start on the online docs, haven't actually done any scala code yet, not sure if there is any demand.

Great work! This will give my G2X even more to do in the studio. Very Happy

Thanks paalolav.

I've updated the live app, made a start on the scala section. No pch2 yet, just the file passing and display. I'm not sure what to do with the mapping. I was going to allow one optional map file per set of tuning files but it might make more sense to have an optional map file for each variation.

The old simplistic docs menu had the unfortunate effect of killing any list you might be working on (because the links were separate pages). I have ajaxed it now so the various documentation pages get inserted into a slider panel.

For those who are not quite so fond of red, there is a monochomatic theme.

The audio tables now have a working delete row button. I'm thinking I might go back to a low clock speed 512 sample per variation template that fits into one VA. Then use use a variation on Tim's ram module to load the samples from consecutive variations for a 2048 sample full audio rate playback.

Has anyone seen a good Dr Who theme midi file that follows the original structure very closely?

Good! Do you integrate middle note, reference note and reference frequency. I know that a .pch2 can not act on the "Master Tune" system setting... But We can manually change the value (from Oscillator or Master Tune) after. When the patch is generated, a value would tell us how many cent to detune the Osc/Master Tune.

The java G2 tool will be very useful for me to make changes on my filter from the scala patch. To adjust my drum roll and so on!

I tried the wav, aiff, rom to .pch2 with your drum machine BIN file collection. It works well! I look forward to further testing.

MIDI to .pch2 : WOW Thanks MAN !!! I love it!


Congratulation! Continue this excelent work. Very Happy

Thanks for the kind words and looking for a Dr Who midi file. I've gone through about 20 so far and can't find exactly what I'm looking for. I might have to find an old midi editor and try myself.

I have been playing with ideas on how to avoid the variation change delay problem with the sample playback.

Here is a patch that uses 16*128 word clocked delays and sequencers that loads each of the 8 variations into the buffer at patch load time.
Then it just loops the 2k sample. What I need is a way of one shot triggering it but haven't found a good solution yet. Perhaps someone else would like to play around with it.

Searchable scala archive now working. I may duplicate this with the drum rom archive later but the binary data might be too much for the postMessage api.

Searches are case sensitive (case insensitivity is a pita with xpath 1) and I need to redo the xml with proper character encoding but mostly done.

Whoa, you added Scala .kbm file support!!! I'll probably test in April after some ongoing stuff settles down.

Thanks so much, Ian, for your continued hard work.

Does that mean we can change the reference frequency ? I only see how to change the reference note. Confused

Edit : I think I understand ... I can choose the reference frequency manually on my patch. It does not affect the ratio between the notes or the reference note.

The code will read a kbm file, but the only part actually used at the moment is the map section. When calculating each tune adjustment value, the code looks up the cent difference from ET for a given note indirectly via the map array. This allows for example, tuning more than one of the 12 notes on the keyboard to the same frequency. I think this would make it easier to play the <12 note turnings. The root or centre note from the KBM does update the onscreen keyboard but as yet it changes nothing in the tuning. I think all I need to do is add ((60-root) mod 12) to the cents lookup then adjust all frequencies octaves by 4 -floor((60-root)/12) or something. Master tuning, including the octave offset would probably just be done by adding a master oscillator module and setting that.

Made some progress with the sample template. I couldn't figure why the sample once loaded from the sequencers would drift on each trigger. All I needed to do was supply if exactly 2048 clock pulses and it should do a full cycle ready for the next trigger right? Turns out 16 * 128 sample memories chained needs 16*127 clocks to do a repeat without drifting.

So here is a demo prf (so I can set the bpm) featuring a DX snare, all 2032 samples loaded from 16 sequencer modules that shift 256 samples per variation into the clocked delay modules.

The loading is a little fragile. The snare should work on start up but if you loose it while adding modules etc, press variation 8 on slot A and it will go through the load sequence again.

I haven't included the new template in the live app. Still working on decoupling the template and code some more.
