Harmony Central Buyer's Guide

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.
