waveTracing Intros SP950 Effect Plugin Delivers ‘Gritty Sound, With Mandatory Aliasing Effects’

waveTracing has released an updated version of SP950, described as an accurate emulation of the SP’s 12-bit 26.04kHz ADC, DAC and detune that delivers ‘gritty sound with mandatory aliasing artifacts.’

Here’s what they have to say about it:

“If you are familiar with the E-mu SP-1200 workflow, you know the way the device is typically used is with a pitched-up source such as a turntable playing a LP record at 45RPM or 78RPM, and a detune after sampling in the SP-1200* to get back to the original pitch and duration. This was initially done to save sampling time, but the resulting artifacts soon became the signature of the device, and of whole musical trend.

This is exactly what the SP950 effect plugin intends to reproduce in a single slider: the RPM/detune slider combines the pitch of the source (markings on the left side, in RPM relative to 33 and in factors) with the detune of the SP (semitons value on the LCD) to compensate each other. The result is a constant duration and pitch output, with varying detune aliasing and bandwidth artifacts.”
