There are 64 Patterns in Pattern Groups A to D, numbered 1 to 16.
  There are 
4 Tracks (=songs), numbered I to IV.
| Mode \ State | during STOP state | during PLAY state | 
| Track Mode | Play drum pads Change Track: [SHIFT] + [I..IV]  | 
    Play selected Track I..IV | 
| Pattern Mode | Edit Pattern | Loop Pattern A1..D16 | 
Play the drum pads 'live' (Track - STOP)
Press the pads, you can use Flam [SHUFFLE/FLAM] and [ACCENT], these work as "shift"-buttons.
  - FLAM only works on the CONGA and TIMBALE pads [3..7].
Edit a Pattern (Pattern - STOP)
| Press [SHIFT] + [PATTERN] 1x or 2x and choose: | ||
| "STEP WRITE" in step write, you select the instrument and press the pad step to place it into the Pattern  | 
    -or- | "TAP WRITE" in tap write, you press the desired instrument pad in time with the Metronome (#8: HI AGOGO)  | 
  
| Same preparations for both modes during [STOP] state. Select a Pattern: - select PATTERN GROUP [A..D] - select Pattern Number pad [1..16] Erase the Pattern: - hold [CLEAR] and press desired Pattern Number [1..16] Copy from another Pattern: - keep holding [SHIFT] and press [COPY] + source location [A..D] [1..16] + [ENTER] - you cannot copy chained Patterns, only single ones Chain Patterns as one Pattern: - hold 2 pads [1..16] and press [ENTER] - both Patterns and the Patterns in between are chained - unchain: hold pad number + [ENTER] for every Pattern in the chain  | 
  ||
| Press [START] - the LED starts looping, the pad row [1..16] now represents the Pattern steps Things you can do, both during STOP and during START: - change from "TAP WRITE" to "STEP WRITE" and back - press [SCALE] to change to 3/4 - half & full Bar, or 4/4 - half & full Bar (see "Scales" below) - hold [LAST STEP] and press [1..16] to change the Pattern length  | 
  ||
|       STEP WRITE Choose the instrument to edit: - hold [INSTRUMENT] and press pad [1..16] or [ACCENT] Press the Pad step to toggle the sound on/off  | 
    TAP WRITE  Toggle the Metronome: - press [INSTRUMENT] Tap the desired pad in time with the Metronome Hold [CLEAR] + pad to erase the sound  | 
  |
|       Flam an instrument: - press [INSTRUMENT] + the desired pad [3..7] two times - press the pad steps you want to Flam Alternate HI CONGA Flam to MUTE (#3) or OPEN (#4): - press [SHIFT] + [INSTRUMENT] Set Flam type: hold SHUFFLE/FLAM and press pad [9..13] Set Shuffle: hold SHUFFLE/FLAM and press pad [1..5] Shuffle and Flam type are stored per Pattern Take care - when changing the SHUFFLE time during play, the TR-707 can lose sync with the master.  | 
    Flam an instrument:  - hold [FLAM] and press pad [3..7] You cannot change the Flam type or Shuffle in TAP WRITE  |

Scales
| Row: | Time: | Length of the Bar: | Set last step to: | Syncs to other x0x gear on: | 
| 4th | 3/4 time | 1/2 Bar (double the notes, double fast) | (4 x 3 Steps) 12 Steps | Step 1 and 7 | 
| 3rd | 1 Bar | (4 x 3 Steps) 12 Steps | Step 1, 4, 7 and 10 | |
| 2nd | 4/4 time | 1/2 Bar (double the notes, double fast) | (4 x 4 Steps) 16 Steps | Step 1 and 9 | 
| 1st | 1 Bar | (4 x 4 Steps) 16 Steps | Step 1, 5, 9 and 13 | 
Note that 3 Steps (notes) in 3/4 have exactly the same duration as 4 Steps in 4/4.
This way you can combine 3/4 and 4/4 beats, and stay in sync, as long as you keep the number of Steps (notes) correct for the chosen beat timing.
Example:
- set the first Pattern to 3/4 time, 1 Bar. Set the last step to 3 (which is one quarter of a 3/4 Pattern).
 
  - set the Pattern next to it to 4/4, 1 Bar. Set the last step to 12 (which is three quarters of a 4/4 Pattern).
- Chain both Patterns
- enjoy the result
Sync steps
The different Roland x0x drum-based gear, like the TB-303 (yes, the programming of the 303 is drum-based), TR-606, TR-707/727, TR-808, TR-909 etc can be synchronized to each other with a DIN-cable. In that case, you also have to make sure you are going to program Patterns that are able to synchronize. You can choose to program 3/4 Patterns and 4/4 Patterns, and even mix these two different Patterns in one Track. The important thing is, that both Patterns synchronize with each other on fixed steps:
- a 4/4 time Pattern has a beat on the 1st, 5th, 9th and 13th step (1-2-3-4, 5-6-7-8, 9-10-11-12, 13-14-15-16).
  - a 3/4 time Pattern has a beat on the 1st, 4th, 7th, 10th and 13th step (1-2-3, 4-5-6, 7-8-9, 10-11-12, 13-14-15).
  - the last 13-14-15-beat on the 3/4 time scale is theoretical, because most 3/4 Patterns have 12 or even 9 steps.
  Both Patterns synchronize on the beat steps, so set the LAST STEP to the step just before the beat step.
  - example: an 8-step 4/4 beat will sync to a 9-step 3/4 beat.
- a 3/4 Pattern that has 11 steps (last step = 11), you will have a sync problem with any 4/4 Pattern.
See the table below for the steps where both Patterns sync.
