The sound Accurate emulation of the SP's 12-bit 26.04kHz ADC, DAC and detune. Gritty sound with mandatory aliasing artifacts.

Detune 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 (semitones value on the LCD) to compensate each other. The result is a constant duration and pitch output, with varying detune aliasing and bandwidth artifacts. Addtional functions: ext. switch extends the detune range from -15 semitones to -30 semitones. fine switch changes detune steps from semitones to tenths of semitones.

Filter Another well-known workflow is the combination of the SP and an Akai S950 low-pass filter to isolate a bass line. The digitally-controlled analog 6th-order Butterworth low-pass filter of the Akai S950 is reproduced here for that purpose, as well as the possibility to mitigate some high-frequency detune artifacts. The filter can be set from 0 to 99 like in the original S950. The filter is defeated when set to 99 (bypass).

Gain Gain in and gain out can be set from -12dB to +12dB, in 0.1dB steps. This can be used to adjust levels based on a given correction, but can can also used to either clip the input section, or keep some margin to increase noise. Additional functions: link. switch maintains a constant total gain when modifying gain in. Total gain can still be modified when the swith is activate by modifying gain out. Total gain is maintained within each gain knob limits (eg +24dB can not be maintained when gain in is lowered).

Signal Routing The routing section located in the plugin's header operates on the signal flow. stereo/mono selector let you choose between stereo, left, right, or summed signals wet/dry knob let you mitigate the impact of the detune artifacts. It is positioned after the stereo/mono routing in the signal flow, so the dry signal is also affected by the selected routing bypass button is equivalent to 0% wet
