VSamp 2.3.0 VSamp is a long-awaited program that turns the Macintosh into an OMS and Sound Manager compatible multitimbral sample playback module. Configured like a simple sampler, VSamp can be setup to playback on 16 MIDI channels with up to 32 samples per channel, mapped and enveloped to user-defined configurations. This can then be driven by an OMS-compatible sequencer such as Cubase, Logic or Vision, or the included application 'OMS Thru' running on the same computer. Output resolution: 8 or 16 bit Output frequency: 11025 to 44100 Hz Sample Resolution: 8 or 16-bit (best with 16-bit) Sample Frequency: any (best with 44.1kHz) Sample Format: AIFF, Sound Designer II (SDII) or Macintosh Sound Resource. Polyphony: up to 32 (computer dependent) voices dynamically allocated Sample mapping: 32 samples per instrument Sample Memory: Depends on memory of computer. Set preferred memory in 'Get Info' in Finder. Multitimbral: 16 instruments per bank assigned to unique MIDI channels. MIDI Implementation: note on, note on velocity, note off (0x9X or 0x8X with 0 velocity), dynamic volume (ctrl 7), dynamic pan (ctrl 10), channel sustain pedal (ctrl 64), channel pitch bend, all notes off (ctrl 123). MIDI compatibility: Requires OMS 2.0 or greater. (free from www.opcode.com) System Requirements * Any powermac or older machine with 68020, 030, 040 processor . Will not run on MacPlus, SE, Classic, Powerbook 100 or original Mac Portable. Best with 16-bit sound as on all powermacs and Quadra 660AV and 840AV. * OMS 2.0 or later (free from www.opcode.com) * Sound Manager 3.1 or later strongly recommended (included with System 7.5.3 and later). * An OMS compatible sequencer or the included application 'OMS Thru'. Polyphony Polyphony is user-defined and depends on the processor speed. The benchmark powermac I have run this on is a powermac 7200/90 (PPC 601 chip) which gives 16 note polyphony for 16-bit 44.1kHz sound without using 'high quality' pitch shifting and 9 notes with the higher quality pitch shifting. Using 22kHz sound will approximately double these values. Faster machines will give more up to a maximum of 32. Please let me know what performance different machines are capable of. If the polyphony is set too high, a disjointed sound will be heard due to breaks between the double buffering. http://www.kagi.com/smaug/vsamp/Download Software
