ASM HYDRASYNTH KEYBOARD Synthesizer with 3 Oscillators

Synthesizer with 3 Oscillators

The ASM HYDRASYNTH KEYBOARD is a synthesizer with 3 oscillators designed to offer the greatest possible flexibility when creating or modifying a patch, aided by an intuitive user interface that allows quick access to every parameter without delving into complicated submenus.
Thanks to an extremely advanced wavetable synthesis engine, featuring 3 oscillators with numerous mutators (FM-Linear, Wavestack, Hard Sync, Pulse Width, PW-Squeeze, PW-ASM, Harmonic Sweep), 2 filters usable in series or parallel, 4 envelope modifiers (HAHDSR), 5 LFOs, an advanced modulation matrix, as well as effects and an arpeggiator, the sound generation capabilities of these synthesizers are unparalleled.
The ASM HYDRASYNTH KEYBOARD is equipped with a PolytouchTM keybed featuring polyphonic aftertouch (independent for each key), for expressive control only possible with some very expensive vintage synths. The 4-octave ribbon controller and the ergonomically designed pitch and modulation wheels ensure performance and control possibilities unlike any other synth.
The 3 oscillators of the ASM HYDRASYNTH KEYBOARD allow choosing from 219 single cycle waveforms. Unlike most wavetable synths, oscillators 1 and 2 of the ASM HYDRASYNTH KEYBOARD feature a WAVELIST that allows selecting 8 waveforms from the 219 available, arranging them in the desired order, and morphing them. Oscillators 1 & 2 are routed to the MUTATORS which allow modulating, bending, and sculpting sound in new or familiar ways.
Each mutator allows choosing from the following processes:

1. FM-Linear – to produce classic FM sounds. Ability to choose from different FM sources, including external inputs
2. WavestackTM – creates 5 copies of the incoming sound with adjustable detune amount
3. Hard Sync – to create typical hard sync sounds. Try syncing a morphing wavetable and start having fun
4. Pulse Width – allows modulating the pulse width of ANY incoming sound
5. PW-Squeeze – different pulse shape capable of creating softer sounds
6. PW-ASM – this mode divides the incoming wave into 8 sections and allows setting the amount of pulse width modulation for each portion
7. Harmonic Sweep – Will sweep the harmonics of the incoming sound from the oscillator

In FM and Sync modes, the mutators can in turn generate waveforms, thus providing an additional oscillator. Of course, the routing is flexible, so if desired, other oscillators can be used as modulation sources.
Signals from the 3 oscillators are routed to a Mixer along with a Noise Generator and a Ring Modulator. The Mixer allows adjusting the level and panpot of each input source.
The ASM HYDRASYNTH KEYBOARD features two filters that can be configured in series or parallel. The first filter has 11 different models, offering more options to customize the sound. The second is inspired by the classic SEM filter, with a 12 dB per octave slope and continuous sweep between low-pass, band-pass, and high-pass.
The ASM HYDRASYNTH KEYBOARD is equipped with 5 low-frequency oscillators. Each LFO features a Step mode that allows creating 8-step patterns. The availability of 5 mini step sequences adds extraordinary possibilities for further shaping the sound. There are also 10 standard waveforms. All LFOs feature delay, fade-in, 3 trig modes, smoothing, start phase, and one-shot mode, which can act as envelopes or sync to BPM.
The 5 DAHDSR envelopes of the ASM HYDRASYNTH KEYBOARD feature delay, attack, hold, decay, sustain, and release. The time setting can be adjusted in seconds or beats, allowing envelopes to operate in sync with the song. It is also possible to loop envelopes to create LFOs whose shape can be voltage-controlled in the modulation matrix.
With 32 user-definable modulation assignments, the 29 modulation sources and 155 destinations can be combined in many ways.
Almost everything in the synth engine can be a modulation destination, including effects and the arpeggiator. The modulation matrix points themselves can also become modulation destinations. Modulation sources and destinations include Mod CV input and output jacks and MIDI CCs.
The arpeggiator allows standard note arpeggios but also features an arpeggio phrase. Parameters like RATCHET and CHANCE will generate other rhythmic patterns with a certain randomness to add vitality and spontaneity to performances. It is also possible to modulate most parameters in the arpeggiator using LFOs, envelopes, polyphonic aftertouch, or the ribbon controller to modify arpeggios in real time.
The ASM HYDRASYNTH KEYBOARD features standard MIDI and USB/MIDI connectivity, and for advanced use, there are also CV/GATE inputs and outputs that allow connection to the modular world. It supports standard voltages for Eurorack modules and some Japanese Volt>HZ products. MOD inputs and outputs allow modulation from DC to the full audio range, further expanding modulation capabilities.
The main system controls allow navigating between patches, configuring system settings, and displaying parameters such as envelopes, waveforms, and filters on the OLED display. The Init and Random buttons allow initializing or randomizing a complete patch or specific modules, simply by holding down the appropriate button + the desired module selection button. Pressing the Home button returns to patch navigation simply and immediately.
In the Master Control section, all parameter changes are performed, patches are named, and macros are executed. Using OLED displays, high-resolution encoders with LED indicators, and 8 buttons, this section is designed to provide good feedback on what is happening. Voice parameters provide access to play modes, analog feel, voice panning, and many other functionalities.
The Macros associated with patches are designed to allow the user deep control of the sound engine in live performances. The 8 assignable encoders and buttons can each be routed to 8 destinations. Complete audio transformations can occur with the simple press of a button or the turn of a knob.
The ASM HYDRASYNTH KEYBOARD comes with 5 banks of 128 patches in total. The 256 patches provided with the device were created by some of the best sound designers around. Finding the desired patch and searching the library is easy with the Browser, while the Patch Manager plug-in, available for PC and MAC, also allows easily moving patches into the desired order and loading new patch libraries.
The effects chain is different from that of other synths, and the Pre and Post effects offer some unique ways to process sound. Delays and reverbs have been modeled on some of the most popular effects on the market.
