Rock Piano

"When all is one and one is all, that's what it is to be a rock and not to roll." ---Led Zeppelin, "Stairway To Heaven"

---

Proof-Of-Concept Piano-Drums Music AI Model/Implementation

---

Model Applications

1. Semi-original Piano-Drums performance generation

2. Semi-original Piano-Drums continuations generation

3. Piano-conditioned Drums generation

4. Drums-conditioned Piano generation

5. Other possible uses

---

Model Details

1. Trained upon ~500 Piano-Drums excerpts which were randomly selected from ~2392 western rock music masterpieces

2. Model SEQ: [channel, delta-start-time, pitch, duration, EOS]

3. Expanded Model SEQ: [channel(0,9), delta-start-time(ms)(0-500), pitch(0-127), duration(ms)(0-500), EOS(500)]

4. MIDI Start time and duration in ticks is converted to milliseconds and then divided by 10

5. Model timings are in milliseconds / 10

---

Model Use Tips:

1. Piano-conditioned Drums generation can be invoked by [EOS, 9] sequence
2. Drums-conditioned Piano generation can be invoked by [EOS, 0] sequence
3. To generate a note at the same time point use i.e. [EOS, 9, 0] sequence
4. To generate a note at the future time point use i.e. [EOS, 9, desired-delta-time] i.e. [EOS, 9, 7] sequence
5. Just in case, EOS == 500, Piano channel == 0, Drums channel == 9
