Tides v1 low acting as pulse / gate only

Picked up a tides v1 second hand a few months ago as part of my first eurorack rig. I always felt like the low output wasn’t working properly. I recently got a dc coupled interface so I could use a scope in my daw and it seems that regardless of the settings, the low output is always just a quick pulse/gate and doesn’t stay open until the envelope is retriggered like it says in the manual.

I believe it had an alternate firmware on it when i got it, and I installed the mutable firmware a few days later.

Am I misunderstanding how it is supposed to work, or is it not working properly? The other outputs all function as I’d expect them to.

Since you have a DC-coupled interface can you record on 3 different tracks:

  1. the signal sent to the TRIG input
  2. HIGH
  3. LOW

With the module set in AD mode, lowest frequency range, all knobs at 12 o’clock.


Thanks for the help :slightly_smiling_face:

I have the 3 audio files here (sorry for the gdrive link, I can’t upload attachments yet) TidesTroubleshooting110822.zip - Google Drive

I realized while capturing these though, that I may have been misunderstanding how the high and low outputs work. I usually have the tides functioning as an LFO in cyclic mode either free-running or with a clock input, and I was imagining the high/low outputs would be outputting a portion of the LFO waveform, but are they actually designed to just be gates for the two phases?

The manual is fairly clear that these are on/off signals!

10. High-tide output. This output goes high (+5V approx.) at the end of the attack phase, and stays at this level until the cycle restarts or the envelope is retriggered.

11. Low-tide output. This output goes high (+5V approx.) at the end of the decay/release phase, and stays at this level until the envelope is retriggered. Both High-tide and Low-tide outputs can be used to chain envelopes.

In cyclic mode, the interval between the end of the decay/release phase, and the moment the cycle is retriggered is very short, so this output is effectively a narrow pulse (which can be used to lock another LFO to Tides1.)

Incidentally these simple gates allow you to easily patch what you described: patch Tides’ BI or UNI output to a 1:2 switch, and use the HIGH output as a control signal.

The same thing could be achieved with two VCAs and an inverter.

If you have a sequential switch (or Stages!) use the LOW output as a reset, and the HIGH output as a clock.

oh that’s interesting! I’ll have to try that.

I’m glad the issue was just an error in my perception of the module. thanks for clarifying!
