The Behringer Edge is a clone of the analog percussion synthesizer Moog DFAM. The analog tone generation is composed of two oscillators, each with triangle and square waveforms, and is capable of FM and hardsync. In addition, the pitch tracking is triple switchable and a decay envelope can be dosed with positive and negative intensity on each tone generator. Additive to this comes a noise generator that offers a choice between white and pink noise. This is followed by a slightly resonant filter that can be switched between lowpass and highpass and modulated with its own decay envelope as well as the noise generator. The signal path is completed by a VCA; this is also equipped with a decay envelope, gets the voltage of the velocity line and two response times. With these features you can create endless combinations of percussive sounds like kick drums, snare, hihats and metallic, but also classic synthesizer sounds. Sometimes it is enough to move a knob a few millimeters and create transitions to other sounds or to completely mutate the running sequence. The complexity of the sounds and modulations expands with the use of the patch panel.

Patch panel

The patch panel, which shares the upper quarter of the user interface with MIDI In and Out/Thru, has 15 inputs and 10 outputs for audio, CV, gate, trigger and clock signals. Each functional area and quite a few secondary functions have their own inputs and outputs. This makes Edge an excellent tool to add oscillators and control voltages to other semi-modular synthesizers and entire modular systems. In turn, Edge eg. can be triggered and modulated by a random sequencer. Additionally, interactions are possible for which there are no controls like modulating eg. Noise Level with the pitch voltage.

Sequencer

There is exactly ONE pattern to work with, the sequencer is a bit anachronistic but a guarantee for performers! If you need banks of patterns and total recall, you won't find it here. Primarily the sequencer consists of two rows of eight steps each: the upper row (Pitch) is used for note input via non-quantized control voltage. The lower row (Velocity) is responsible for a large part of the dynamics as it affects the VCA and mutes the step when the knob is turned to the left. The sequencer can be synchronized to MIDI, USB or an external Clock . With MIDI respectively USB the Clock divider/multiplier is active at the same time, so it's easy to play beatsynchronous with different timings. The internal clock generator reaches far into the audio range which can be musically quite interesting. The patch panel outputs the control voltages generated by the internal sequencer.
