Quick concepts
Every Session contains 16 Patterns. You can chain and repeat Patterns on a timeline to create a Song.
Every Pattern contains a sequencer for one realtime Synth and 6 Session-wide Drum Samples.
The realtime Synth can also have some Automation (aka "Motion recording").
You can create the 6 global Drum samples with a virtual MS-20. However, the realtime Synth is unique for every Pattern.
Every realtime Synth in every Pattern can have its own realtime Effect. The Synth Patch can also be different for every Pattern.
Effects on the Drum sample are part of the sample.
Finally you can balance the 7 Tracks with the Mixer, and assign which Tracks receive a globally chosen Effect.

Schematically it would look like this:

A bit more verbose concepts

A Session contains:
- 16 different Patterns and a global mixer with one chosen realtime effect
- 6 global Drum samples, which you can create with a virtual Synth
- a Song that can hold 256 Patterns
- Patterns that hold 7 Sequencer Tracks: 1 for the realtime Synth and 6 Tracks for the different Drum samples

The Pattern properties are
- for every Pattern there is 1 realtime Synth with a unique Patch
- every Pattern has a 7 Track 16-step SQ-10 Sequencer: a Track for the Synth and 6 Tracks for the 6 "Drum" samples
- every SQ-10 Sequencer Track in the Pattern has its own settings (eg. loop points)
- every Sequencer Track can record Note, Gate, Volume and Pan

The Synth in each Pattern has some unique properties
- it is rendered in realtime, during Play
- the SQ-10 Sequencer for the Synth can also record 3 extra Automation Tracks
- the Automation parameters can be chosen, controlled and recorded with the KAOSS Pad
- the Automation can be edited with the Synth Sequencer screens
- the Synth has a Synth panel and a Patch panel with virtual patch cables.

The 6 global Drum sample players have the following properties
- there is a special Synth to create the Drum Track samples: it lacks the 2 "Release" Envelopes and no Tempo Sync for the MG.
- a Drum sample can have a maximum sample time of 1 second.
- you can also add one Effect (Delay, Chorus or Flanger) to the Sound.
- the Synth sound and the Effect is merged into the sample
- the Sample is centered on Note C4
- the 6 samples are part of the Session, every Pattern uses these 6 samples
- there is no automation possible for the samples

All the Synths are monophonic.

The difference between the possibilities of the realtime SYNTH Patch and the sampled DRUM sounds:
- when you play the SYNTH Patch 3 octaves down, you get a good quality low note with the same duration.
- when you play a DRUM sample 3 octaves down, you get a low note with 3 times the duration, also the FX is slowed down.

Properties for the Song
Patterns are the building blocks the Song. You can chain and repeat Patterns into a Song.
The Song Patterns are sent through the Mixer and Effects.

Pattern settings versus Session settings
The SYNTH Patch is part of every Pattern, so you create the Patch for the Synth inside every Pattern. This way the SYNTH Patches can be different for every Pattern. However, Drum Patches, the Effects and the Mixer settings are (global) Session settings.
