BLEASS Motion FX offers a new and creative workflow to effects sound design.

BLEASS Motion FX contains 11 different effects which you can modulate precisely thanks to an intuitive and comprehensive sequencer.
Choose an effect and dynamically modulate it thanks to an intuitive and versatile motion sequencer. Thanks to its very low CPU usage, load as many instances of Motion FX as you want and unveil new sonic territories!

Effects included are:
- Low Pass Filter
- High Pass Filter
- Band Pass Filter
- Volume
- Pan
- Pitch Shifter
- Frequency Shifter
- Ring Modulator
- Warmth
- Bit Crusher
- Delay

Each effect has a parameter automated by the sequencer and can have one or more secondary parameters. Pick an effect and then modulate it dynamically thanks to the motion sequencer. When switching effects, the motion sequencer keeps its state to invite you to new sound design ideas!


The sequencer offers 4 to 16 steps, each step has a value and a curve. You can set the value by touching and/or dragging the step and set the curve by tapping the curve icon at the bottom of each step. Curves choices are: Step, Ramp Up, Ramp Down, Ramp and Smooth Ramp.
- Length controls the number of steps (4 to 16).
- Resolution controls the duration (in bars) of each step. (from 1/32 bar up to 4 bars)
- Grid snap: when set to ON, steps values snap to the displayed grid when you change their values.
- Reset: resets all steps to their default values (default value depends on the current selected effect).
- Amount sets the sequencer’s amplitude.
- Randomness sets the range in which step values are randomly chosen.
- Smooth sets the interpolation time between steps.


- Low Pass Filter, High Pass Filter and Band Pass Filter:
The sequencer modulates the frequency value of the filter.
A slider controls the resonance of the filter.

- Volume:
The sequencer modulates the gain.

- Pan:
The sequencer modulates the pan.

- Pitch shifter:
The sequencer modulates the pitch. The pitch range is +/- 12 semitones.
Grain Size sets the density of the granular pitch shifter.
Grid sets the sequencer grid to Chromatic, Major or Minor. Set Grid Snap to ON to quantize the pitch to the selected scale.

- Frequency shifter:
The sequencer modulates the frequency. The frequency range is +/- 1kHz.
Fine adds an offset to the frequency set by the sequencer.
If Stereo is On, Fine value for the right channel is the opposite to the left channel.

- Ring modulator:
The sequencer modulates the frequency. The frequency range is 1Hz to 10kHz
Fine adds an offset to the frequency set by the sequencer.
If Stereo is On, Fine value for the right channel is the opposite to the left channel.

- Warmth:
Warmth is a waveshaper. The sequencer modulates the strength of the waveshaper.
Drive adds a gain before the waveshaper.

- Bit crusher:
The sequencer modulates the rate of the bit crusher.
Depth controls the depth of the bit crusher.

- Delay
The signal is delayed by a time set by the sequencer. The time range is 0 to 50ms.
Feedback sets the amount of delay feedback.
When Ping Pong is On, the delayed signal bounces back and forth between the left and right channels.
Stereo sets the difference between left and right delays.

- A Dry/Wet control lets you set the balance between the dry and wet signals.
- The random preset generator (dice button next to the presets manager) only affects the parameters of the current selected FX.

Another superb BLEASS app

Great sounds loving the presets so far! I can see using this on a lot of tracks! Thanks for another great ☝️ I’ll update my review once I delve deeper.

Needs a less random random

Dig the app, the fx are pretty good though intentionally don’t have the most in depth control. This is well worth the $ if you’re into beat-sync’d effects.
I think it would greatly benefit from a panel to let you pick what to randomize - I keep getting situations where I hit the dice but it suddenly doesn’t sound like anything is going on either because the mix is suddenly 5%, or the onset envelope time ends up being longer in ms than the effect’s BPM*Division. Ie a delay that kicks in after 40ms doesn’t happen if the onset is suddenly set to 450ms - that is math that could be checked but really I would prefer if I could get it so only the envelopes and random%s would change but leave the #of steps, division of bpm, and MIX%(!) alone.
