Measured against atlantis drums.mp3 at the verified +76 ms alignment, using your own 17 confirmed rim clicks as the reference timbre. Limits of each measurement stated beside it.
The kick count is roughly right. The tom lane is wrong, and the rim clicks are hiding inside both.
Two different problems get blamed on one symptom. Counting them separately:
| Lane | Notated in v13 | Attacks found in that band | Notated hits with no matching attack | Read |
|---|---|---|---|---|
| Snare (control) | 288 | 719 | 26 (9.0%) | This is my detector's own error floor |
| Kick | 486 | 546 | 73 (15.0%) | About 29 beyond the floor. Not wildly over-counted |
| Tom | 98 | - | 23 (23.5%) | Nearly triple the floor. The real problem |
So kick is not the over-count you might expect: 486 notated against 546 detected attacks in the 40 to 110 Hz band. What is wrong with the kick is labelling, not volume.
I took your 17 confirmed side sticks and measured their timbre, then did the same for 376 confirmed kicks and 203 confirmed snares. The energy split is the whole story:
| Confirmed class | Low 40-110 Hz | Body 120-350 Hz | Click 1.2-4 kHz | Air 7-15 kHz |
|---|---|---|---|---|
| Your rim clicks | 0.529 | 0.277 | 0.127 | 0.051 |
| Kick | 0.712 | 0.185 | 0.049 | 0.059 |
| Snare | 0.148 | 0.541 | 0.157 | 0.104 |
Your rim clicks put 53 percent of their energy in the kick band.
A rim click on this kit is not a thin sound. It sits at 0.529 low against the kick's 0.712, so in the low frequencies the two are neighbours. Any transcriber that leads with low-frequency energy will hear a rim click and write a kick. That is exactly the confusion you asked about.
The feature that does separate them is the stick click at 1.2 to 4 kHz: 0.127 for a rim click against 0.049 for a kick, a factor of 2.6. Nothing in the pipeline so far has used it.
The tom lane is where the transcription put anything that was neither clearly snare nor clearly cymbal. Three separate things are sitting in it:
Bar 76 accounts for 10 of the 23 phantom toms on its own. Removing that one bar's mislabel would take the tom lane from 23.5 percent down to about 13 percent, close to the control floor.
You said the rim clicks run to bar 84. Here is what the file carries against what the audio contains, counting stick-click attacks in the 1.2 to 4 kHz band:
| Bar | Notated hits | Stick attacks in the audio | Notated lanes |
|---|---|---|---|
| 76 | 17 | 11 | 12 high tom, 4 kick, 1 snare (the toms are your rim clicks) |
| 77 | 17 | 11 | 13 side stick, 2 kick, 1 snare, 1 hat |
| 78 | 20 | 10 | 4 side stick, then hat, kick, ride take over |
| 79 | 25 | 12 | 7 kick, 4 hat, 4 ride, 2 high tom, 4 crash, 4 snare |
| 80 | 29 | 13 | 8 kick, 5 hat, 4 ride, 3 high tom, 8 snare |
| 81 | 21 | 11 | 9 kick, 4 hat, 3 ride |
| 82 | 22 | 10 | 11 kick, 4 hat, 4 ride |
| 83 | 20 | 9 | 8 kick, 4 hat, 4 ride |
| 84 | 19 | 6 | 6 kick, 5 hat, 4 ride |
| 76-84 | 190 | 93 |
The side stick label stops at bar 78, and from bar 79 the same repeating figure is written as kick plus hat plus ride. That matches what you are hearing. The other chat told you the rim clicks stop at 77 and called the rest hats and ride, which is the same mistake in the other direction.
Caveat on the 190 against 93: a kick played alone produces very little energy at 1.2 to 4 kHz, so some of that gap is real kicks the click detector cannot see. Treat the ratio as a signal that the outro is over-written, not as a proof of exactly two to one.
The stem separation stripped the rim clicks out of the outro.
You said the rim clicks run to bar 84. The isolated drum stem shows none at all after bar 78, which is why every stem-based analysis, mine included, called that lane hats, ride or kick.
So before calling you wrong I ran the identical scan on the full mix. The side-stick signature is built from your own 17 confirmed strokes: click at or above 0.100, air at or below 0.080, low at or above 0.400.
| Threshold, bars 79-84 | Drum stem | Full mix |
|---|---|---|
| click ≥ 0.100 | 0 | 17 |
| click ≥ 0.085 | 2 | 23 |
| click ≥ 0.070 | 13 | 34 |
| click ≥ 0.060 | 18 | 39 |
The rim clicks are in the song. They are missing from the stem. At every threshold the mix carries far more of them, and at the strict threshold the stem carries none.
Stated fairly in both directions: the mix contains guitar and bass, so a click with low-end could also be a pick attack, which makes 17 an upper bound rather than proof. And the mix scan finds 0 in bar 77 where 13 rim clicks are confirmed, because other instruments mask them there. Neither source alone is complete. They are complementary, and your ear is the tiebreak.
| Change | Evidence |
|---|---|
| Bar 76: all 12 high toms became rim clicks | 10 of 12 had no tom-band attack, 4 stick-signature attacks present in the stem, timbre matches your confirmed strokes, and you said it at 19:26 |
| Bars 79-83: 16 hits relabelled to rim click | Placed at the full-mix stick attacks, snapped to the 16th grid. Taken from hats, ride and toms |
| No kick was touched | You said they are not kicks, and the outro kick lane measures click 0.034 to 0.051, which is the kick signature, not the stick's 0.127 |
| Check | v13 | v15 |
|---|---|---|
| Side sticks | 17 (bars 77-78) | 45 (bars 76 through 83) |
| Kick | 486 | 486 untouched |
| Snare | 271 | 271 untouched |
| Toms | 90 | 85 |
| Beats needing 3 hands | 0 | 0 |
| Ghost dots / accents / flam | 100 / 65 / 1 | 100 / 65 / 1 |
| Distinct durations | 6 | 6 |
| Velocities on the GP ladder | yes | yes |
One honest gap: bar 84. You said the clicks run to 84. At the strict threshold neither the stem nor the mix shows a stick attack in bar 84, so v15 carries them through bar 83. Extending them one more bar on your ear is a one-line change and I will make it the moment you say the pattern is there.
My first v15 attempt was quarantined rather than deleted. It converted only 16 scattered hits and introduced 3 three-hand beats: quarantine/Sean_song_v15_FIRST_ATTEMPT_3hand_regression.gp5.
Every claim in the v15 review was re-measured against the file before anything was changed. Six were real, one was overstated, one measured the wrong property.
| Claim | Verified? | What I measured | v16 |
|---|---|---|---|
| 9 closed + open hi-hat pairs at bars 14, 37, 39, 40, 61, 65, 66, 68, 72 | Exact | 9, in exactly those bars | 0 |
| Snare and side stick together in bars 79, 80, 81, 83 | Overstated | Only 1, in bar 83. Not six. | 0 |
| Crash and ride stacked, bar 79 and bar 80 | Confirmed | 4 stacks: 3 in bar 79, 1 in bar 80 | 0 |
| 58 crash notes inherit an earlier dynamic | Confirmed, and it was mine | 51 of 86 crashes sat at velocity 95, because I hardcoded it when building your bars 16-21 pattern | 6 levels |
| Bells should accent above the surrounding ride | Confirmed for 5 | Bells at bars 25, 26, 27, 57, 78 sat at or below the local ride level | lifted |
| "Zero ghost note flags" | Wrong property, third time | That flag draws the parentheses you rejected. You asked for the dot, which is the staccato property. v15 and v16 carry 100 staccato dots. | unchanged by design |
None of these were coin flips. Each used a measurement calibrated on unambiguous hits in this same recording:
| Conflict | Measurement | Calibration | Outcome |
|---|---|---|---|
| Closed or open hat | Air sustain, the 7-15 kHz tail at 90-260 ms against the first 50 ms | open-hat median 0.864, closed-hat median 0.667 | All 9 measured above the cut, so the open hat was kept in every case. Beat 4 is where a drummer opens the hat, so the closed note was the spurious one. |
| Snare or side stick, bar 83 | Stick click share at 1.2-4 kHz | side stick against snare medians | Measured 0.103, so the side stick was kept |
| Crash or ride, bars 79-80 | Air sustain, crash rings longer | crash median 0.947, ride median 0.820 | All 4 below the cut, so the ride was kept and those crashes were spurious |
| Crash dynamics | Measured attack energy per hit, mapped onto the GP ladder | 8th and 92nd percentile of the crash population | 66 crashes re-voiced, spread across 6 levels |
| Check | v15 | v16 |
|---|---|---|
| Closed + open hat on one beat | 9 | 0 |
| Snare + side stick on one beat | 1 | 0 |
| Crash + ride on one beat | 4 | 0 |
| Beats needing 3 hands | 0 | 0 |
| Crash velocity spread | 51 of 86 at one value | 47:13, 63:17, 79:24, 95:15, 111:4, 127:9 |
| Ghost dots / accents / flam | 100 / 65 / 1 | 100 / 70 / 1 |
| Kick / snare / side stick | 486 / 271 / 45 | 486 / 270 / 45 |
| Velocities on the GP ladder | yes | yes |
For the Ableton stage: Sean_full_song_v16_plus76ms.mid carries all three tracks (Rhythm Guitar 1404, Drums 1438, Bass 478) at the +76 ms alignment, with the corrected per-hit velocities intact so an acoustic kit's velocity layers respond to them.
The likely root cause of all of it
The drum part descends from a Songsterr AI-generated tab, and every version since has been editing that inherited transcription rather than re-deriving the drums from atlantis drums.mp3. That explains a low-band-driven kick lane, a tom lane used as a catch-all, and rim clicks scattered across three labels. The fix is a re-derivation from the stem using the click feature, not another round of edits.
You asked why the drum sheet has more toms and kicks than you actually hear. I measured it, and there are two different answers.
The kicks are mostly fine in number. The sheet has 486 and the recording has about 546 thumps down low. So it is not inventing loads of kicks. The problem is what it is calling them.
Here is the trick. When you hit the rim of the snare, that sound is much deeper than you would think. More than half its energy is down in the same low rumble where the kick drum lives. So a computer listening for "low thump" hears your rim click and writes down "kick drum". They are neighbours down there.
The way to tell them apart is the little wooden tick sound up high, around 2000 Hz. A rim click has about three times more of that tick than a kick does. Nobody has used that yet.
The toms are the real mess. The tom row became a junk drawer. Bar 76 says twelve tom hits, and ten of them are not toms at all, they are your rim clicks. Another nineteen "toms" elsewhere turned out to be cymbals. So the tom row is holding three different instruments.
And you were right about the ending. The rim clicks are written properly only in bars 77 and 78. From bar 79 to the end, that same pattern got written as kick and hi-hat and ride instead. So they do carry on like you said, they are just wearing the wrong names.
Why it all went wrong: this drum part started as a computer guess made from the whole song at once, not from the drums-only recording. Everyone since has been fixing that guess instead of starting over from the clean drum track.
