SP web app
Please note: development has been stopped due to unreliable audio latencies in current web browser implementations. The desktop version which was based on a similar plateform is also stopped, but will be replaced with a VSTi version that is under development. The present web application remains freely available, but does not reflect the current state of the SP audio engine as used in the future VSTi version.
OverviewThe SP web app is a free access web application that runs in modern browsers (see compatibility section below). It is currently in very early alpha stage, lacking a lot of functionalities. A Windows/Mac standalone desktop version is also developed in parallel, with similar functionalities, and will be available for purchase once the functionalities reach a certain usability point. The SP web app combines the well-known 12bit workflow with its distinctive detune algorithm together the famous 6th order low-pass filter. It is not intended to be a clone, but a reimagined device that holds on to what makes this unit so special in both its sound and workflow, while adapting it to a screen-based interface.
- Faithful SP sound in a browser
- 6th order low-pass filter
- 8 pads with detune slider
- 8 channels mixer
- pre-sample speed option (45RPM, 78RPM)
- load most common audio formats
- save detuned sample in wav format
RPM/detuneThe E-mu SP-1200* was often used 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.
The speed option serves this exact purpose, appling a pre-sample pitch that can be compensated for using the detune slider.
It was also often used in combination with the Akai* S900 or S950 6th order low-pass filter.
