Feedback that ends in one thing to do next
Updated 3 August 2026
Every take ends with a verdict, up to three things that specifically slipped, a map of which bars went wrong, and exactly one recommended next action.
One action, not a list — because the failure mode of practising alone is not a shortage of information, it is having no basis for deciding what to do with it.
What you get after a take
- A verdict
- Groove cleared, almost there, keep practising, or check your setup first. Plain language, no axis jargon.
- The coach read
- Up to three prioritised observations about what actually slipped, ordered by what matters most.
- A bar map
- One cell per bar, coloured by how that bar went, so you can see where it fell apart rather than guessing.
- One next step
- Repeat these specific bars, slow it down, take one more clean take, or move on — with a button that does exactly that.
- Per-skill evidence
- For each skill the groove actually tested: what you scored, and how far that is from the pass mark.
- Per-note markers
- Green, orange and red dots on the notation itself, so you can trace a score back to individual hits.
Then it picks what comes next
Passing a groove is not a fixed threshold on one number. Every skill the groove was written to test has to clear its own mark, and a skill that could not be measured does not silently count as a pass.
Once you clear it, the next groove is chosen from your measured weakest skill relative to where you are heading. There is no hand-wired curriculum graph — the recommendation comes from what the charts actually contain, constrained so the step is never more than one level, never jumps straight from quarter notes to sixteenths, and never overshoots in complexity.
It also adapts to how the take went. Scrape a pass on one skill and the next step is deliberately smaller; clear everything comfortably and it opens up.
The seven skills
- Note accuracy
- whether the notes the chart asks for actually landed, with extras counted against you
- Timing with the click
- how close each hit sits to the grid while the click is running
- Internal pulse
- whether the tempo holds through a section where the click drops out
- Timing stability
- how tightly your hits cluster around your own average, independent of being early or late
- Dynamic control
- whether ghost notes, normal hits and accents land in the zone the chart asked for
- Dynamic range
- how much real contrast there is between your softest and loudest notes
- Limb independence
- whether the feet keep up with the hands, or one side falls apart

Common questions
How is this different from a metronome app?
A metronome tells you where the beat is. It has no idea what you played. iQuantize compares every note you played against what the chart asked for and tells you what to change.
Does it just give me a percentage?
There is a headline number, but it is supporting evidence rather than the point. The verdict, the prioritised observations and the single next action are what the screen is actually built around.
What if I disagree with the feedback?
Check the per-bar map and the per-note markers — they show exactly which hits drove the result. Most disagreements turn out to be a mapping problem or monitoring delay rather than scoring: check the pad mapping first.
Does it ever tell me nothing?
Yes, deliberately. If a take does not contain enough evidence to judge a skill, that skill reports nothing rather than a number. An honest blank is more useful than a confident guess.
