yes it is a wave based synth engine, that uses GeneralUser GS samples as a basis. it is not literally an sf2 soundfont player, but it uses the same samples and loop points.

Are there any features that had to be dropped from the GUGS soundfont to fit into the Pango?

All instruments are there, including all 13 drum kits. To fit in flash every sample is stored with ADPCM compression, mostly at 22 kHz (cymbals and hi-hats at 32 kHz), and a lot of it was tuned by ear on the hardware. It runs on my own engine, not FluidSynth — simplified, but the instruments, layers, envelopes and drum kits are all there, with 48 voices of polyphony plus reverb and chorus. Compared to the SoundFont on a PC it sounds a little warmer and grittier, more 90s. It is based on GeneralUser GS samples but it doesn't sound identical.

I had developed different synth engines and am still testing what will be in picopango, as i want to combine multiple engines for more choice.
so for now i change the specs to 'multiple engines' -- will update soon with the final descriptions.
Once it is more finalized, i will also record some demos. (too busy right now)
