ProTrekkr (formerly known as NoiseTrekker by Juan Antonio Arguelles Rius aka Arguru) is
a tracker program combining a software synthesizer together with a traditional samples
tracker which can be used to create electronic music (like psytrance, trance goa,
hard acid, IDM, chip, techno, etc.) for small sized intros, demos or games.

v1.93:

- Resampler improved, should produce much less aliasing.
- Fixed a small issue involving the cache memory in the PSP replay.
- Added an option to show or hide the bottom panel in order to display more patterns rows (Shortcut: LSHIFT+ESCAPE to toggle the view)
- Left shift wasn't active while editing data columns of patterns to enter digits.
- Added global lists for instruments and synths, that should improve the ergonomy a bit.
