I made a short video on youtube. in a realy bad quality, because i do not have fancy video equipment.
It is a 8 voice sampler, where you can record a sample an habe this one sample pitched over the entire keybard.
there is an ADSR for cutoff, amplification and pitch. there is only one ADSR and it can be switched with a switch. than there is a simple saw/sinus oszilator for tunig the samples pitch and also for sound creation.
The sampled are looped and start of the sample and the loopspeed can be adjusted. I think thats is. the is a (hidden) LFO. it only can be used with MIDI stuff.
