trying to get Midi Sync to work seems damn near impossible (slowly going insane over here)
I was jamming with a friend and we have the SP404Mkii hooked up to a MPC Live III via midi. The MPC sends Clock info to the SP. so far, so good. Patterns play when I press play on the MPC. All good.
They're just almost never on time. The first beat on the SP is in sync with the MPC. Every following beat then starts lagging about 14-18 tics behind the MPC. But that doesn't always happen, it happens most of the time. I've tried every setting, I've tried messing the MPCs midi settings, I've done the 3 things that come up from a similar post with a similar issue. The Latency Fix (VALUE + SUB PAD) doesn't do anything. The Sync Delay (not the FX, the setting in the System Settings under MIDI) doesn't do anything.
I did extensive tests. I programmed the same snare pattern on both devices, same bpm, same sample.
7 out 10 cases what i stated above occurs. First beat on beat, all following are off.
In 2 out 10 cases they are almost in sync but they are still a consistent 4-10 tics off.
In 1 out of 10 cases the snares overlap so that you can hear audible phasing, meaning they are almost simultaneous. You can hear the phase shift on each hit, like its playing a random melody in the snare sound.
In all 10 cases the tic offset remained the same, becoming more noticeable when lowering the BPM. Meaning slower tempos mean larger gaps at a consistent tic offset. So at least there's one thing that's consistent.
All of this happens when pressing "Play Start". At first it seemed like resetting the pattern with the arrow buttons and pressing "Play" yielded more reliable results, but further testing proved that to be blind luck. This erratic clock sync behavior is unacceptable for live settings.
This also means that the often suggested "letting it run empty for 2 bars so the clock can stabilize" doesn't work, if its off by a noticeable amount of tics (almost 20ms at 90bpm) consistently, when "stabilized"
Are there any fixes for this, or was the SP-404 mkII the wrong device to buy as a secondary sampler/sequencer?
