Frequently Asked Questions

This is a one-time iOS permission request for the AUv3 plugin to access the standalone app's Documents folder. Tap the blue "Enable Files App Access" button, locate the folder for Augmatic GRE on "My iPad," and press Open. Without this, presets saved in the AUv3 won't be visible in the Files app. See File Storage for details.

Make small, incremental changes and listen carefully. The app is designed to create evolving patterns — moving many knobs at once can sound chaotic, while subtle parameter adjustments produce more musical results.

This is almost always a BLEND interaction. For example, if BLEND is fully left (Grids only) and the Grids DENSITY for a given channel is also fully left, that channel outputs nothing — even if Euclidean PULSES are set high, because Euclidean notes aren't being used at that BLEND position.

Both engines can also be muted by the Linear Drumming matrix — if a channel has low priority (dot on the right) and other channels play frequently.

Augmatic GRE is a MIDI-only plugin — it does not produce audio. You need to:

1. Make sure the MIDI notes it outputs match the notes your drum sampler or synthesizer expects. You can select output MIDI notes on the Settings tab.
2. Use the built-in MIDI mappings or create a custom mapping for your instrument, then save it so you don't have to repeat the setup.
3. Route each channel's MIDI output to the appropriate sound in your drum engine.

BD', SN', and HH' are accent channels that correspond to the main BD, SN, and HH. In the original Grids design, accent channels represent weaker backbeat elements and are intentionally triggered less often. To reproduce that behaviour, set accent DENSITY to around 25%.

In Augmatic GRE, you're free to use accent channels however you like. Push them into more aggressive territory with DENSITY above 25%, or use them to create longer accent phrases across several bars by setting CLOCK to /2 or /4.

When you give slower accent channels higher priority in the Linear Drumming matrix, GRE produces far more interesting, evolving patterns instead of the typical repetitive 1-bar loops.

Turn BLEND to full right (Euclidean) and set the Euclidean params to 16 steps, 16 pulses, Start On 1. This will output fast 16th notes.

BLEND crossfades the probability between the two engines:

• Full left → only the Grids engine (XY Map) generates notes.
• Full right → only the Euclidean engine generates notes.
• Any position in between → a probability mix (e.g. 12 o'clock = 50/50 chance of a note coming from either engine).

If BLEND is fully left, Euclidean PULSES settings have no effect — and vice versa.

Yes. The Master Chaos slider (located under the XY pad) is designed for this. Bump it up to introduce variation and fills, then bring it back down. Since it's an exposed AUv3 parameter, it can be automated from a DAW.

Other tips for fills:

• Bumping the Master Chaos slider produces fills that are coherent with the base pattern (since they derive from it).
• A super-slow LFO on the Master Chaos slider can create evolving song-level structure.
• Record MIDI output while manually moving the slider to capture fills at specific points.

Linear drumming limits how many hits can occur at the same moment, making the groove feel more human and intentional. Instead of BD, SN, HH and their accent channels all firing together, you choose which channel wins the step by moving its dot to the left in the Matrix. The farther to the right a dot sits, the lower its priority — higher-priority instruments will mute it and it will only play when no other channel is playing at that moment.

Not exactly. Linear Drumming is not a classic choke feature. When an instrument is set to a higher priority, it chokes all instruments with lower priority — not just a specific paired instrument.

For proper choke behaviour (e.g. open hi-hat cut off by closed hi-hat), use the choke feature in your drum sampler or synth.

Swing creates a shuffle/groove feel by delaying every other 16th note. If your pattern doesn't contain any 16th notes, you won't hear the effect. To test it, turn BLEND to full right (Euclidean) and set 16 steps, 16 pulses, Start On 1 to get a fast 16th-note pattern that reacts to SWING changes immediately. Increasing CHAOS can also force the Grids engine to add some 16th notes.

Augmatic GRE can't predict what the Grids engine will play ahead of time — for example, before you turn CHAOS up. To move a pattern "forward" (ahead of the beat), GRE delays that channel's clock by 1 bar minus x, where x is the forward-shift amount. This makes it possible to create flam-style hits: a grace note that lands just before the main stroke, giving the sound more weight and character.

Caveat: Adjusting SHIFT in real time or through automation — especially when crossing the centre point — can produce unexpected results. The parameter is still available for automation, since subtle movements work well.

Open the Files app and go to On My iPad / On My iPhone → Augmatic GRE → Presets or MIDI Mappings. Rename the XML file directly.

Not directly. If you want to start from a pattern and return to it later after changing some parameters, save it as a preset and recall it when needed. Future versions of Augmatic GRE will make this easier for live performance.

Yes, all knobs support double-tap to reset to their factory default. You cannot set a custom default position.

Correct — the Init preset isn't empty. It's a simple four-on-the-floor starting point in both the Grids and Euclidean engines. From there, everything you do will only make the pattern more interesting.

Yes. All parameters are exposed as AUv3 parameters and can be automated from any compatible host DAW.

• Super-slow LFO on Master Chaos → creates evolving song-level structure automatically.
• Automate XY pad position → morph between different drum pattern topologies over time.
• Automate individual density/chaos → build and break down patterns for verse/chorus transitions.

Yes! All parameters in Augmatic GRE can be automated, including the MIDI OUT notes for each lane (BD, SN, HH, etc.). This means they can also be targets for randomization.

To set it up in AUM:

1. Tap the hamburger icon to the left of Augmatic GRE, then select the “faders” icon (AU Parameters) from the menu on the right.
2. You’ll see a full list of parameters — the MIDI Note parameters (BD MIDI Note, SN MIDI Note, HH MIDI Note, etc.) are near the bottom, ordered tab by tab following the GUI layout from left to right.
3. For each note parameter, you can assign a CC number. If you have a plugin sending Sample & Hold values via CC, that signal will randomize the note — which is exactly what you’re after.
