PetSynth
From Wikipedia, the free encyclopedia
PetSynth is an open-source music software for the Commodore PET computer, created in 2008 by Chiron Bramberger.[1][2][3][4][5][6][7][8][9][10][11] It is noteworthy for being the only keyboard playable synthesizer for the Commodore PET that supports stereo sound and is released under a GPL license.[1][2][3][4][7][9][10] It has been featured in print and web publications such as Return Magazin,[2][8] TPUG Magazine,[1] Commodore Free Magazine,[3] Retrothing,[4] and MatrixSynth.[5][6]
History
Chiron Bramberger created PetSynth after discovering similar software for the Apple II, Apple IIGS, VIC-20, and Commodore 64.[1][4][7] The first version of PetSynth was released in 2007.[1][2][3][4][5] Since then, there have been several revisions, with the third version demonstrated at the TPUG World of Commodore in 2013.[6][7][9][10][11]
Features
The original version of the software allowed a user to play on the keyboard layout as if it were a musical piano keyboard.[1][2][3][4][5] It included several effects that allowed the player to change the sounds in interesting ways as they played.[1][2][5] The third version, as of 2013, included support for a MIDI adapter, and a second voice feature never before realized.[6][9][10][11] This allowed for stereo sound on a Commodore PET for the first time.[6][9][10][11]
