PSPSeq

DSP Music has released version 3.0 of PSPSeq, a free homebrew application for composing music on the Sony PSP handheld game system.

PSPSeq contains both realtime synthesis and sample playback capability, along with multiple FX modules of widely varying types for modifying instruments in countless ways. PSPSeq also has a powerful and unique step sequencer for triggering samples and arranging loops into full songs.

Key features of PSPSeq:

• up to 16 independent audio tracks per song
• a wide variety of synthesizers from traditional virtual analog and FM to Karplus-Strong
  and unique digital oscillators with parameter controls rarely seen in commercial synths
• WAV file playback with looping, pitch shift, and configurable start/end points
• many FX algorithms from digital filters and waveshapers to bitmasks and decimation
• all synthesizer parameters can be set to unique values on a per-step basis
• step sequencer with configurable step length, swing, highly accurate BPM, and tap tempo
• probabilistic sequencing: the decision to retrigger to be based on a 0-100% probability
  rather than a boolean yes/no operation
• song sequencing with 100 different loops per song, 1000 measures per song, and loop
  repeat capability
• load and save of synthesizer presets between songs
• record loops and songs to WAV
