Comparison
iQuantize vs Melodics for electronic drums
Updated 3 August 2026
Melodics is built to keep you playing. iQuantize is built to make you play better.
Melodics wraps practice in points, streaks and a scrolling note highway, and it is genuinely good at getting you to show up. What it never tells you is whether your playing changed — because it grades whether you hit the note, not how you hit it.
iQuantize measures the playing itself: which side of the beat you land on, whether your ghost notes stayed ghosts, whether your time holds when the click stops, whether the feet keep up when the hands get busy. Seven skills per take, named in plain teacher language, and the next groove chosen from whichever one is weakest.
You will not get a streak out of it. You will get a drummer who is measurably better in six months.

What that buys you
Six differences that decide whether a month of practice actually changes how you play.
You read real music, not a falling-block game
iQuantize puts engraved drum notation on screen — the same staff a teacher writes on, a band hands you, or an exam board prints. A moving playhead follows the bar and every hit gets a green, orange or red dot on the note itself, live, as you play.
A scrolling note highway is easier on day one and teaches you nothing you can carry. Learn to read while you practise and you can sit behind any kit, in front of any chart, and play. That skill outlives whichever app you are using this year.
Seven skills measured, not one score
Most apps answer one question: did you hit the note near enough? iQuantize measures your take on up to seven separate skills — note accuracy, timing with the click, internal pulse, timing stability, dynamic control, dynamic range and limb independence — and scores only the ones the chart actually contains.
That is the difference between a mark and a diagnosis. One number tells you the take was 78%. Seven tell you the notes were right, the hands were steady, and the kick drifted late as soon as the hi-hat went to sixteenths — which is a problem you can go and fix tonight.
It takes the click away and watches what happens
Playing tightly to a metronome and having time are different abilities, and the first one hides the absence of the second. On grooves written for it, iQuantize drops the click mid-take, scores those silent bars separately as your internal pulse, and brings it back so you can hear where you ended up.
A wide gap between your two timing scores is the finding: you have been practising reaction, not time. It is the single most useful thing a teacher checks and almost nothing else measures it.
A coach's verdict, then one thing to do
Every take ends the way a lesson ends — a plain-language verdict, up to three prioritised observations about what actually slipped, a bar-by-bar map showing where it broke, and exactly one recommended next action.
One, not a dashboard. The failure of practising alone is not a shortage of numbers, it is having no basis to decide what to do with them.
The next groove is chosen for you, from your own data
iQuantize embeds every groove in the library as a vector describing what it actually trains, then picks your next one by nearest-neighbour search from your measured weakest skill — constrained so the step is never more than one level, never jumps from quarter notes straight to sixteenths, and never overshoots in complexity.
Scrape a pass and the next step shrinks. Clear everything comfortably and it opens up. There is no hand-wired lesson order to fall off: the path is built from the content and from you, which is what a teacher does between lessons.
It refuses to invent a number
When a take does not contain enough evidence to judge a skill, iQuantize reports nothing for it rather than a confident guess. A groove with no dynamics in it produces no dynamics score; a take where the notes fell apart will not pretend to grade your timing.
An honest blank is worth more than a plausible number, because you are going to spend an evening acting on whatever it tells you.
Find out what your playing actually looks like
Connect your kit and play one take. You get a verdict, the bars that went wrong, and the one thing to fix next.
Requires an electronic drum kit or a MIDI-capable drum module.
What we deliberately do not do
Every one of these is a choice, and each one is the reason the app works the way it does.
You get told you passed only when you actually did
iQuantize does celebrate. There is a day streak for turning up, and a moment when you clear a groove. What there is not is a points economy, a level ladder or a leaderboard — because those pay out for playing, and playing is not the same as playing well.
Clearing a groove here means every skill that groove was written to test has met its own pass mark. Not an average that a strong backbeat can drag over the line, and not a participation tick: a skill the app could not measure honestly does not quietly count as a pass. You cannot grind your way through it, and you cannot get there by turning up.
That is the whole difference. A reward for the session tells you that you played. A reward gated on seven measurements tells you that you improved — and it is worth something precisely because it can be withheld.
A graded curriculum, not a content firehose
The library is deliberately smaller than a catalog and deliberately ordered. It is informed by drum method books, graded exam paths and teaching sequences, and each groove introduces exactly one new element — ghost notes, an open hi-hat, a syncopated kick, a shuffle feel.
Thousands of lessons sounds like value until you are the one choosing between them. Choosing badly is the most common way self-taught players stall, so iQuantize takes the choice away and spends its effort on knowing what you should play next.
Native on Apple, and that is a feature
iQuantize is one native codebase for iPhone, iPad and Mac, talking straight to CoreMIDI with hardware timestamps on every note. There is no browser layer and no cross-platform runtime between your kit and the scoring.
When the product is timing measured in milliseconds, the stack it runs on is not an implementation detail. It also works fully offline, with no account, no email and no password.
Where Melodics is the better buy
- A much larger catalog. If your goal is a long list of songs to play along to, Melodics has far more of them and adds more every month.
- It covers keys and pads too. One subscription across three instruments is real value if you play more than drums.
- It runs on Windows. iQuantize is iPhone, iPad and Mac only and there is no Windows version planned — so if you practise at a PC, Melodics is the one you can actually use.
What iQuantize costs. 14-day free trial. Pro's planned launch price is €14.99 a month or €120 a year (save 33%), VAT included. A free tier keeps the Starter grooves after the trial. See the full breakdown.
Common questions
Is iQuantize just Melodics without the fun?
It is a different product with a different goal. Melodics is designed around engagement — the streak, the score, the next unlock. iQuantize is designed around diagnosis: read the chart, play the take, find out which of seven skills is actually holding you back, and get one specific thing to fix. If you already practise regularly and cannot tell what is wrong, that is the gap this fills.
Does the smaller library mean less value?
The library is graded rather than large — each groove adds exactly one new element, in an order informed by drum method books and exam paths. The value is not in how many items exist; it is in never having to choose which one to practise, because the app picks it from your measured weakest skill.
Can I use both?
Yes, and some players do — Melodics for volume of playing, iQuantize when they want to know why something is not improving. Both read the same MIDI from the same kit, so there is nothing to reconfigure.
Do I need to read music already?
No. The notation is on screen every take with a playhead following it and colour on each note, which is how reading is actually learned — alongside playing, not before it. There is also a notation guide in the app.
