BLEASS Monolit combines the rich analogue sound and intuitive ease-of-use of BLEASS Alpha with the creative expressiveness of BLEASS Omega. The result is a compact, efficient, mono-synth tailor-made for creating thunderous basses, searing leads, sparkling arpeggios and other-worldly SFX.
And it’s completely free!


OUTPUT – Controls and visualises the instrument’s output level.

Volume: Sets the desired output level

Meter: Visualises the current peak output level of the instrument

VOICE – Provides access to basic voicing parameters

Detune: Sets a master detuning that affects the entire synth, in the range ±0.5 semitones.

Retrig: Enables or disables the retriggering of ADSR envelopes when playing legato

Vibrato: Sets the rate, in milliseconds, of the global pitch vibrato

Amount: Sets the strength of the global pitch vibrato. A setting of 100% means the global tuning will oscillate between -1 semitone and +1 semitone.

Pitch Bend: Determines the maximum pitch bend range, in semitones.

Glide: Sets the time taken for the synth’s pitch to ramp from the last-played note to the currently-played note.

UNISON – BLEASS Monolit includes a Unison algorithm that creates up-to seven duplicates of synth’s voice. With detuning applied, this creates a thicker, fuller sound.

Voices: Sets the number of voice duplicates to create, from 0 to 7.

Detune: Sets the amount of detuning to apply to the unison voices. The detuning is spread amongst the voices, with a setting of 100% meaning that the most-detuned voice(s) will be 1 semitone above and/or below the played note.

Target: Choose whether to apply the unison algorithm to both oscillators, or only one or other of them.

MODULATION – Route incoming Mod Wheel, Slide and Pressure messages to Monolit’s parameters. Each controller source can be routed to two destinations.

Mod. Wheel: Responds to standard MIDI modulation wheel messages (MIDI CC 1)

Slide: Responds to note-specific CC-74 messages received from MPE-compatible controllers. In BLEASS Monolit, Slide’s behaviour is set to relative.

Pressure: Responds to MIDI Aftertouch messages, produced by changing the pressure being applied to the key of a compatible keyboard or controller.

Destination Selection Menus: Use the destination selection menus listed under each modulation source name to choose the synth parameter that should receive the controller messages.

Amount Dials: Scales the strength of the controller message being routed to a synth parameter.

ARP – Configure the built-in arpeggiator

State: Enables or disables the arpeggiator

Mode: Sets the sync mode of the arpeggiator.

  • FREE uses an internal timer that is set within the instrument.
  • SYNC synchronises the arpeggiator to the host DAW’s beat.
  • BEAT synchronises the arpeggiator to the host DAWs beat and synchronises the arpeggiator’s pattern position to the host’s bar-and-beat location.

Rate: Sets the speed of the arpeggiator.

  • In FREE mode, the rate is set in milliseconds
  • In SYNC and BEAT modes, the rate is a factor of the host DAW’s beat length.

Mode: Determines the pattern of notes that the arpeggiator will produce.

  • NORMAL: Notes are played in the order in which they were triggered.
  • UP: Notes are played in pitch order, from lowest to highest.
  • DOWN: Notes are played in pitch order, from highest to lowest.
  • UP/DOWN: Notes are played in succession, from lowest to highest, and then back to lowest.
  • RANDOM: Notes are played in a random order

Octave: Sets the number of additional octaves that the arpeggiator should cover. When set to “0”, only the triggered notes will be played. When set to “1”, notes that are one octave higher than the triggered notes are added to the arpeggio; higher settings add further octaves.

Gate: Sets the duration of the arpeggiator’s notes, as a proportion of the arpeggiator’s rate setting.

Repeat: Sets the number of times each note is repeated before the arpeggiator moves on to the next note.
