Review: Innerclock Systems Sync-Gen II Pro

Rory Dow on Sep 21, 2012 in Review 0 comments

Despite wanting to mix totally in the box, many musicians rely on much loved MIDI hardware… but how to keep everything in sync with your DAW? Enter Innerclock System Sync-Gen II Pro. Rory keeps time.

Electronic musicians have always enjoyed the mix of software and hardware instruments. The DAW is so powerful these days that entire albums can be made and mastered on a single computer, but the pleasure of playing a real instrument is something that a DAW cannot fully emulate. And so studios around the globe mix the latest software hosts and instruments with hardware sequencers, synthesizers and drum machines. The tricky part is getting them all to play nicely together. If this sounds all too familiar to you, then read on...


That syncing feeling

The Innerclock Sync-Gen Pro II does a simple job. It provides rock solid, sample accurate MIDI clock and DIN sync from your DAW host.

Back in the early 1990s, electronic musicians mostly used the Atari ST computer for sequencing and life was good. The Atari had MIDI ports which were connected directly to the motherboard, which meant solid timing and low latency. The computer and its connected instruments synced up beautifully.

Eventually the PC and Mac superseded the Atari ST. The PC was more powerful and musicians were tempted by infinite tracks of audio recording, virtual instruments and all the other non-music related stuff that PCs did so well. One of the downsides of PCs is that MIDI was no longer built in. MIDI interfaces had to be bought separately and were connected via serial ports and eventually USB and Firewire. This had a detrimental effect on MIDI timing and latency. With all the other things the computer was doing, MIDI timing was no longer such a priority in the system. This wasn’t the fault of software engineers, but more a limitation of the hardware itself.

This problem of MIDI timing remains to this day. Regardless of how good the DAW software and hardware MIDI interface are, MIDI timing is still subject to the jitter and latency introduced by the PC/Mac hardware. If you have ever tried to sync a drum machine or sequencer to MIDI clock coming from your DAW, it’s very possible you will have been frustrated by the results. At worst the timing is awful, but sometimes clock jitter and latency can leave a feeling that something “isn’t quite right”.

The simple solution

Innerclock’s solution is simple: remove the job of generating MIDI clock from the computer to a dedicated box. The Sync-Gen II Pro is a rather beautiful item. It has two audio inputs, a footswitch input, a trigger output, 5 MIDI outputs and 5 DIN sync outputs (DIN sync is an older sync standard used by Roland in the 1980s). The audio inputs receive pulses created by the Sync-Gen II software plugin running in your DAW and these pulses are converted instantly to MIDI clock and DIN sync. Because DAW audio is sample accurate, this means you get sample accurate conversion to MIDI clock.

With this sample accurate clock the 5 MIDI and 5 DIN sync ports can be used to accurately sync any hardware which uses these protocols.

Plugin control

Innerclock’s Sync-Gen II software comes in VST, AU and RTAS plugin format on Mac and PC and is included in the price of the unit. The software not only sends the sync pulses to the hardware box but also cleverly deals with start/stop messages, so all your hardware will start and stop along with the transport on your DAW host.

The Sync-Gen II plugin sends audio pulse signals to the Sync-Gen II Pro box, which are converted into MIDI and DIN Sync signals.

The basic function of syncing your hardware to your DAW with 100% reliability would probably be enough for most, but the Sync-Gen II software goes further, allowing several more useful functions:

  • Swing can be applied to the sync pulses, and therefore the generated MIDI and DIN sync, which means swing can be applied to machines which never had that feature.
  • Sync can be offset to counter any internal latency that your hardware might be subject to. Drum machines with digital sequencers can suffer from this. It’s often only a few milliseconds, but being able to dial in an exact advance/delay means you can get any machine in perfect sync.
  • Pattern rate can be changed to allow machines to playback in multiples or divisions of the current tempo.
  • An internal “bar sequencer” allows up to 8 bars to be sequenced, each with its own transport, swing and rate settings allowing for some very creative manipulation of the clocks.


Setting up

When you first receive the Sync-Gen II Pro, the setup is surprisingly minimal:

  1. Plug in the power supply.
  2. Connect two audio cables from your soundcard to the Sync and Transport inputs on the Sync-Gen II Pro box. A soundcard with a minimum of 4 outputs (total) is needed.
  3. Connect your hardware instruments to either MIDI or DIN sync outputs as appropriate.
  4. If you want to use the trigger outputs (to synchronise any analog sequencers or modular synthesizers) connect the included Y-Split adapter to the Trigger output and make connections to your hardware.
  5. Launch your favourite DAW host and insert the Sync-Gen II software plugin on an audio track. Set the audio track’s output to the pair of outputs on your soundcard to which the Sync-Gen II Pro box is connected.


You can be up and running in 20 minutes or less. Sometimes the signal level of the plugin might need adjustment depending on your soundcard. Mine works best with a +6db boost.

Conclusion

During the first session with the Sync-Gen, I was grinning from ear to ear. It’s not that MIDI sync from Mac and PCs doesn’t work. It does, but there’s often this feeling that something isn’t quite right. With the the Sync-Gen II Pro, drum machines, sequencers and synths suddenly sound tight and musical. Everything just “locks in”. I found myself hands in prayer position saying “Thank you Innerclock!”.

Being a fan of hardware instruments, and someone who spent years frustrated by the lack of musical satisfaction syncing hardware to software, the Sync-Gen Pro II has become indispensable in my setup. It’s not a cheap solution, but when I think that I will never again have to tear out my hair trying to sync two worlds together, it suddenly seems like money very well spent.
