Monitoring

MIDI Monitor

MIDI Monitor is a free studio tools VST plugin developed by rs-met. Compatible OS(s): Windows 64b.

MIDI Monitor is a plugin which shows you the incoming MIDI messages. Because some hosts treat instrument- and effect-plugIns differently (and do not allow plugging one kind of plugin into a slot of a different kind), there is an ‘instrument’ and an ‘effect’ version of the plugin to make it pluggable everywhere. The MIDI-events are passed through unchanged, the same holds for any incoming audio signal.

Dual Channel FFT

Dual Channel FFT is a free metering plugin developed by Christian Budde. Compatible OS(s): Windows.

Dual Channel FFT is a program that analyses the spectral difference between two measurement points. This can be useful to measure the electro- and acoustical chain during a live performance.

Additionally the program can visualize the processing of VST Plug-ins, export the frequency response to TXT/BMP and export the impulse response to WAV.

Dual Channel FFT is free for non-commercial use.
