Future Retro - Transient


Transient is a sample-based drum module with innovative sound design capabilities. It contains more than 400 recordings of rhythm machines and analog synthesizers. Two sample channels can be combined. Amplitude and ring modulation, a multimode filter plus effect algorithms allow users to process sounds in various ways. Potentiometers, control voltage inputs with attenuators and a total of nine random CV generators can be routed to several parameters. Due to a 12 bit digital to analog converter, Transient sounds a lot like vintage rhythm machines. On top of that, the results are very lifely, thanks to continuous timbre variations. Transient can generate classic to modern drum sounds as well as glitches. By modulating the sample selection and / or the integrated mixer, users are able to generate entire drum loops with one of these modules.



Transient is a rather complex drum module. However, once users have understood all its components and the signal flow, operating the circuit is fairly easy. There are 40 storage slots for saving presets. Internally, Transient works with a resolution of 16 bit. A 12 bit analog to digital converter was implemented to add some vintage character. Furthermore, samples are continuously subjected to small phase and amplitude changes. The result is an extremely natural, lively sound.

Transient comes equipped with the following synthesis components:

Voice 1 / Voice 2: These are the sample players of the Transient module. As soon as a signal is detected at the module’s trigger input, both stages begin to play back the selected samples. More than 400 audio snippets of classic drum computers and analog synthesizers are available. The sample selection can be influenced via the Transient’s CV inputs, knobs and / or a random generator.

Mod 1 / Mod 2: The sample players are followed by so-called Mod sections. Here, musicians will find a volume control and a mute option per voice. Using the Transient’s Mod oscillators or the respectively other sample channel, it is possible to create amplitude or ring modulation effects. Amplitude modulation can not only be utilized for altering the timbre of sounds, but to create fades, envelope sweeps and tremolo effects as well. Particularly complex results are achievable with connecting the Mod stages in series.

Mod Osc 1 / Mod Osc 2: The modulation oscillators can be used as envelopes with loop function, LFOs or audio generators. Their frequency range goes from 0 Hz to 20 kHz. With the sync option activated, the modulation oscillators will reset to a selectable phase value each time a trigger signal is detected by the Transient. In addition to standard waveforms, special envelope waves are available. Frequency and phase of the modulation oscillators can be manipulated via the CV inputs, knobs and / or a random generator.

Mixer: Sample players and Mod sections are followed by a mixer, which can be controlled via the CV inputs, knobs and / or a random generator. – Perfect for creating sound layers, crossfades or playing both sample channels alternatingly.

Effects: The Transient’s effects section offers bit crusher, distortion and compander algorithms. The ladder can be used to give drums the sound of rhythm machines from the 1980s.

Filter: The multimode filter features high-pass, band-pass and low-pass algorithms. Additionally, there is an all-pass mode, which could also be described as a bypass mode. The cutoff frequency can be influenced via the CV inputs, knobs and / or a random generator. A resonance parameter is not available. However, high-pass and low-pass are supplemented with a little resonance automatically.

Dynamics: A final VCA, which can be controlled via the CV inputs, knobs and / or a random generator. Minimum and maximum dynamic values are editable.

CV input 1 / CV input 2: The control voltage inputs are equipped with attenuators. They can process signals in the range of 0 V to +5 V.

Knob 1 / Knob 2: Transient features two potentiometers, which can edit a multitude of parameters. (See above) The knobs are also usable for adding an offset to the CV inputs or random generators. All other control elements of the Transient are assigned to a specific function.

Random generators: In total, Transient comes equipped with nine random generators. They generate new random values each time a trigger is detected.
