Behringer JT-4000M Micro Synthesizer

Compact synth power for on-the-go ideas and spontaneous sounds

The JT-4000M Micro from Behringer is a mini synthesiser that follows in the footsteps of the Roland JP-8000. With its compact dimensions, it is barely larger than the logo on the original keyboard. In addition to its handy size and a control layout stripped back to the essentials, another special feature is its hybrid sound generation, which can be played in four-voice or paraphonic mode. You’re unlikely to compose any trance anthems on the 16-key capacitive keyboard, but it’s perfectly adequate for trying out the sounds. The hybrid sound generation is largely modelled on Roland’s JP-8000, which remains very popular to this day and was first released in 1997. The two virtual-analogue oscillators provide Supersaw, 2-OP FM, ring modulation, noise, and, of course, the classic waveforms: square with PWM, sawtooth and triangle. Instead of the digital multimode filter, there is an analogue 12 dB low-pass filter, with the VCA completing the signal path. As with the original, modulation is handled by two ADSR envelopes, two LFOs, velocity and the arpeggiator with three playback patterns. However, the fully authentic JP-8000 sound is not achieved, as the JT-4000M Micro primarily features a completely different filter design and has no on-board effects. Power supply and data exchange with the app take place via the USB port. This M version features a built-in MIDI-TRS socket, through which the JT-4000M Micro can receive MIDI notes and data from other MIDI equipment. Furthermore, it boasts comprehensive MIDI implementation and includes 32 memory slots for your own sounds.
