Whoops. I will describe a simplified test that I just performed on my Tempest that conveys the issue I've observed.
SETUP:
- Slave Tempest's MIDI Port to DAW's MIDI Beat Clock.
- Optional: Configure DAW's MIDI Beat Clock. Helps to hear that sync is maintained, when hearing clicks from both DAW & Tempest
- Set DAW to 120 bpm, 44.1 kHz, 256 buffer size, time signature to 4/4
- Initialize Tempest Project
- 16 Beats Mode
- Beat 1: change time signature to 4/4, and Beat length of 1 measure.
- copy Beat 1 to pads (aka, Beats) 2-10.
- no need to actually record a sequence to the Beats. (Do so, optionally, if desired.)
- Playlist mode, Events screen:
- for following Playlist, let all steps be 1 measure
- create Playlist of 10 steps, so that for each number n,
step n=Beat n.
So,
step 1=Beat 1,
step 2=Beat 2,
step 3=Beat 3,
...
step 9=Beat 9,
step 10=Beat 10.
step 11=nothing
- Set Playlist End to "Stop Playback".
("Loop to Step 1" gave me same results.)
More "rules" for testing consistency:
- Always begin DAW from stop.
- On DAW, only begin at the 1st or 3rd beat of a measure.
- Tempest buttons/modes during test:
16 Beats lit
Playlist lit
Events lit
Click on
HYPOTHESIS:
- Playing DAW from a beat 1 or best 3, from any measure between 1-10, and Tempest Playlist's measure should soon correspond to same measure as DAW. Moreso, as each Playlist step is 1 measure, and consists of consecutively ordered Beats 1-10, the Playlist step # and Beat # should soon correspond to DAW measure #, after pressing play on DAW. This should happen, no matter the measure 1-10, the DAW is started from.
RESULTS:
- Starting DAW before measure 9, Playlist plays as expected.
For example, beginning on DAW measure 3,
beat 3: by DAW measure 4, beat 1, Tempest playlist plays step 4, which is Beat 4 (pad 4 lights), and Playlist measure 4.
Also, beginning on DAW measure 8, beat 3: by DAW measure 9, beat 1, Tempest playlist plays step 9, which is Beat 9 (pad 9 lights), and Playlist measure 9.
- from any of these pre-'measure 9' start points, Playlist plays to end as programmed.
However:
- Starting DAW on or after measure 9, Playlist plays step 2 at the 1st beat of the 2nd measure after starting DAW. This is unexpected.
From this point onward, Tempest plays its Playlist as programmed; but this doesn't correspond to where it is supposed to be relative to DAW.
For example:
Beginning on DAW measure 9, beat 3: by DAW measure 10, beat 1, Tempest playlist plays step 2, which is Beat 2 (pad 2 lights), and Playlist measure 2.
Another example: beginning on DAW measure 10, beat 1: by DAW measure 11, beat 1, Tempest playlist plays step 2, which is Beat 2 (pad 2 lights), and Playlist measure 2.
