Same here.
overclocked, no waveforms in CCM. no filter. Algo 27 and 28. held down 2 keys.
I did not notice any glitches either.
Great. I'll try and get some better measurements at some point to see how close to the limit we are.

I started adding my own wave and got this when I compiled. Any ideas?
src/synth/Osc.cpp:108:1: error: too many initializers for 'WaveTable [8]'
You'll need to adjust #define NUMBER_OF_WAVETABLES in Common.h to 9.
Then add the type to enum OscShape in SynthState.h (before _LAST) and the name to the oscShapeNames list in SynthState.cpp:189 and you should be good to go.

What you can do is leaving the existing waveforms in CCM and adding your new one in regular RAM.
Not to run out of regular ram.

Awesome!! got it working. added the new waveform.
heads up, on my mac, when I went to add the name to the oscShapeNames list in SynthState.cpp:189, my text editor kept on changing the character used for " and it would not compile. it took me a while to figure that  the character was being changed.

So basically what I did was sample a waveform I liked to use as raw material on audacity. Trimmed it to one cycle. Made it mono. used sample data export. I made sure that the single cycle was 1024 samples based on the sample rate and the frequency/pitch of the sound. Then I added a space and commas after every single entry using Excel.

Then I added this data to the waveforms.c. I then changed #define NUMBER_OF_WAVETABLES in Common.h to 9.

The I edited waveforms.java. Then added the type to enum OscShape in SynthState.h (before _LAST) and the name to the oscShapeNames list in SynthState.cpp:189.

I compiled. . . and yay!! lots of fun.

Great!
I wouldn't have thought to use Excel to convert data :D

old thread i know...

so is the procedure the same with the newer firmware (i want to try to add more than 6 new waves)? do i add to waves.c?
waves2.c is not needed, right? i can compile the firmware even if i rename/move this file. also no need to edit waveform.java, right?

thanks.

EDIT: nevermind i figured it out. but i overflowed ram by adding all the tables i wanted :-) hehe.
