Are there any VST Instruments which allow sampling?
There have been no major commercial releases of VST-compatible samplers yet, although NI’s Reaktor can be used as a sampler and can also run as a VST Instrument. However, a few shareware and even freeware ones are available. For instance, S&C Develop (www.multimania.com/scdevelop/syntha.htm) have their SC Virtual Sampler, already at version 2.1. Remember that you’ll need plenty of system RAM to run your applications, and that you’ll have to leave enough spare for sample storage — 128Mb is an absolute minimum, while 256Mb is more suitable for serious sampling work.
