We need some good graphics for the main sampler screen. This is where you can do rudimentary editing of the samples that are played in the sequencer.
There are two screens. The main screen with the controls:

• Volume (this one may be changed later)
• Speed (Playspeed. The sample also pitches up or down)
• Filter (in the middle the sound is unchanged, away from center it engages either hi-pass

hi,
as you know, in SoLoud, the number of filters are limited
we should implement more like different reverbs, fir and irr filters, (these could be used to implement HRTF support), Chorus, One Poll, One Zero, Pole Zero, Two Pole, Two Zero, etc
a library exists called stk under zlib license which already implemented these maybe we can implement some of these out
