Main characteristics :
Accurate emulation of a 12-bit 26.04kHz SP ADC, DAC, and detonation. Grainy sound with obligatory aliasing artifacts.
If you are familiar with the E-mu SP-1200* workflow, you know that the unit is usually used with a source with a pitch, such as a turntable playing an LP record at 45 or 78 rpm, and after sampling into the SP-1200* detuning is performed to return to the original pitch and duration. Initially, this was done to save sampling time, but the resulting artifacts soon became a characteristic feature of the device and the whole musical direction.
This is exactly what the SP950 effect plug-in intends to reproduce in a single slider: the RPM/detune slider combines the source pitch (marks on the left, in RPM relative to 33 and in factors) with the SP detune (the semitone value on the LCD) to compensate for each other. friend. The result is a constant duration and pitch output, with varying detune aliasing and bandwidth artifacts.
Note that the actual pitch remains unchanged.
switch ext. extends the detonation range from -15 to -30 semitones.
the fine switch changes the detonation steps from semitones to tenths of a semitone.
Another well-known workflow is the combination of SP and the Akai* S950 low pass filter to bring out the bass line. Reproduced here is a digitally controlled Akai* S950 Butterworth 6th order analog low-pass filter for this purpose, as well as to be able to mitigate some high-frequency knock artifacts.
The filter can be set from 0 to 99, just like the original S950. The filter is disabled when set to 99 (Bypass).
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 equalization, but can also be used to clip the input section or save some headroom to increase noise.
The link switch maintains a constant overall gain when the gain is changed.
The overall gain can be changed while the link is active by changing the gain out.
The overall gain is maintained within each gain control (for example, +24dB cannot be maintained when the in gain is reduced).
Signal Routing:
The routing section, located in the header of the plugin, controls the flow of the signal.
In addition to the dry/wet and bypass functions, the layout selection menu allows you to specify how the input signal is converted and processed, for example
The layout selection does not affect mono signals, except for the Stereo Side option, which in this case is equivalent to bypass.
The Stereo L/R/Mid/Side layout options only affect one signal component, leaving the other untouched. You can include a second instance of the plugin in the chain to process an additional component with a different set of parameters.
The wet/dry knob is located after the layout selection in the signal flow, so the dry signal is also affected in the case of a mono conversion.
the bypass button is equivalent to 0% wet.
The minimalistic interface is fully compatible with HiDPI/Retina displays for crisp visualization. Its size (enlargement or reduction) can be changed without using the menu in the upper right corner. The color scheme of the LCD can be selected from 6 presets using the small button to the right of the LCD.
Scale selection affects all instances of the plugin on a given machine and is automatically reflected in running instances.
Aside from aesthetic considerations, the choice of LCD color can be used as a visual cue to distinguish between multiple instances of a plugin in a project.
Ableton users with a HiDPI display on Windows may want to uncheck “Auto-Scale Plug-In Window” in Ableton’s right-click menu to get crisp rendering.

Changes v1.3.0 2022-06-25 :
– Reduced CPU usage (around -20% at 44.1/48kHz sample rate)
– Reduced filtering noise.
– Improved GUI responsiveness on macOS with Retina displays.
– Middle click sets sliders to default value, same as double click.
– No longer disables gain binding when adjusting output gain.
– Various UI adjustments.
New opportunities:
– Load/save configuration from/to the clipboard in the menu.
bug fixes:
– Fixed issues with sampling rates of 176.4 kHz and above (eg using the new Reaper oversampling feature).
– Plugin bypasses and freezes when using Randomize function in FL.
