apulSoft have released apTrigga, a Mac OS X VST Effect plugin that generates a trigger signal from an audio source. This signal is used to trigger mono Samples (AIFF & WAV), which can be dropped directly onto the plugin interface. apTrigga features an extensive filter section to extract specific frequencies from the source material. Velocity and a 4-pole low-pass filter can be modulated by the trigger intensity.

apTrigga can be used to replace recorded drum instruments with sampled drums, to extract rhythm elements from drumloops or to spice up drum mixes with short attack-samples. Due to its zero sample latency apTrigga works great for live drum triggering.

Main Features:

• Triggers mono samples by an audio signal.
• ZERO samples trigger latency.
• Output can be modulated by level and a lowpass filter.
• Drag 'n' drop support for AIFF and WAV sample files.
• Anti-aliased sample display.

apTrigga is available for $30 USD
