Hello, I’m trying to sync my Hapax with Logic Pro. I’d like to use the method described in the manual: Share Audio synchronization from a DAW: enable sample-rate precision. While this works perfectly with Ableton Live, I can’t get it to work properly with Logic Pro, especially when I want to change the tempo. Is it even worth trying to get it working? Has anyone succeeded? I get the impression that Logic struggles with controlling external hardware and properly handling plugin delay compensation.
audio is audio, a sample player playing a square wave sample should have none or almost no latency.. i have gotten this method working in various software so no reason it shouldnt work in logic [audio]
Yes it works in Logic Pro with the sample provided in the instruction, but only with the tempo at 120bpm. If I change the tempo in Logic, the sync is lost unlike in Ableton (with warp in repitch mode) where sync is tight
You could try using a dedicated plugin to generate the audio pulse instead of a looped sample - I use the Midronome VST found here which I originally had running to send a signal to a Midronome. Once I got the Hapax with its CV in sync, the Midronome became redundant.
Works great for me
the signal output level needs to be close to maximum for it to work well and your audio device needs to be dc coupled
also, the cv clock sent by logic will not change the internal tempo of hapax. you are only starting the next division of time in hapax. hapax is still performing the sequence at internal tempo, and your clock pulse simply starts the next slice according to the receiving rate set in hapax settings. if you want all potential events to be realized, hapax has to bet set to the same tempo internally as logic. either that or dont place midi in hapax piano roll at over 64th note resolution, assuming youre receiving cv cock at 64 pulses per measure.
i don’t use CV so there maybe workarounds as an incoming audio signal but as a general rule Logic hasn’t been able to receive incoming sync (at least MIDI Clock) for several versions now. which may be why it’s also rebelling against CV?
one of those midi sync distrobution devices like mentioned earlier is probably a good buy for your setup. if you cant get cv clock working that is. although they use the same mechanism done the same way.
given a stable midi clock, hapax plays very well. also midi clock from hapax is pretty solid even if im clocking hapax with cv from reaper or live. its the best ive experienced honestly.
confirm the audio from logic is coming from a dc coupled audio device. it may not be. also try turning up levels to hapax. even clipping since its only a square wave. it wont hurt your sound device.
My audio interface has a dedicated clock output (Arturia AudioFuse 16Rig). In Logic Pro I open the sync settings and set the clock to the 16Rig clock output. This works real well but I wish I could still control the Hapax sequencer playback when set to sync to analog in
I’m getting good results with the Midronome plugin (thanks to Martino for the tip 
) as a VST directly on a dedicated output of my Apollo X6. I can also adjust the delay on the MIDI track in Logic to compensate for external latency. I tried something similar with the ERM Multiclock plugin, but strangely enough, no good results.
What’s crazy is that I can’t get the MIDI coming from the Hapax (for example, a note every beat to drive a VST Drum synth) to sync in Logic, while the audio from synths sequenced by the Hapax is recorded in Logic perfectly in sync. The same setup with Ableton Live controlling the Hapax gives both audio AND Midi in sync
