It seems like no other application that samples knows what they are doing compared to this! Instuments can have sustained loop points, you can create your own soundfont, and the sound quality is truly amazing! It isn't stated in the description, but this is polyphonic fun and the volume, slides, and cutoff are impressive. Would like the ability to record to wav and export via wifi. Would also like Resonance as an effect and maybe a customizable arpeggiator, but the sounds and fun with this is truly worthwhile and rewarding. Definitely fills the gap for polyphonic sampling with looping and all people who like music programs should have this. I was going to get a midi keyboard for soundfont sampling in my computer sequencer, but this does the same thing better, faster, and with more options while being amazingly portable. Thank you for this program!
