H90 dub style delay using send level

Being able to assign ‘send level’ to the quick knob would allow me to momentarily crank up the delay send level – then quickly turn it down again and the delay effect on the output of the looper would continue – dub style. (There would be loads of feedback already set up)

It seemed a little awkward to use a Quick Knob for this.  I don’t use them much beyond System settings.  I tried various In & Out Gains, Mix controls, Series, Parallel … None of them really covered all your criteria.

The simplest way would be to use a Perform switch.  For Preset B, Bypass (M) or Bypass, and save the Program just like that.  I’m assuming that you have DSP selected in the Global – Program Bypass Mode.

The Program will load with Preset A Looper active and audible.  Pressing Preset B – Bypass (M) will kick in the delay following the Looper.  Releasing it back to Bypass keeps the ‘loads of feedback’ trailing after it.

Not really a send, as much as a solo switch.  As an alternative, Repeat (M) will perform in much the same way, but the delay mini-loop will be quickly gated when you release the switch.

I’m guilty of assuming that everyone uses at least one EXP pedal with the H90, so I left that option out.  It’s one of the more versatile & controllable ways to get you where you’re going.

For similar uses, I usually target the Feedback parameters directly for external control.  Just be careful with the maximum range limits.  If your selected delay algo goes from Feedback 0-110, you can often hit self-oscillation by the upper 90’s.

With an EXP or AUX / HotSwitch mapping, I tend to place a little bit of Feedback at the default minimum range (around 5 or 10).  That forces a smoother fadeout when approaching EXP – heel, or H/S release / OFF.

It would also allow for a background slapback on the looping.  Preset B Mix & Feedback(s) set fairly low, then both mapped to increase greatly under foot control.

… I have an ‘elektron analogue heat + fx’ effects unit … (By way, the use case here is for vinyl DJing – I have the h90 connected to the send and return on my dj mixer. )

Nice rig, and to me, an interesting H90 application.  You may already have some other options available, for mapping the ‘swell’ over MIDI.

Hi again! When you said to ‘use a perform switch’ – do you mean a foot switch or even a hotswitch? Cheers

Yes I do. I tend to group everything you can find by clicking on the PERFORM knob and the 3 corresponding LEDs as perform switches.  I’d include the use of the Bypass (M) in the 1st example.

• Map one or many parameters to a HotSwitch, for instant transitions.  As a parallel, jumping immediately from Heel to Toe on an EXP pedal, skipping the values in-between.  It can have a momentary action, or latch & unlatch.
• When using multiple HotSwitches, clicking on one overrides the rest.  It’s possible to set up 4 unique “Programs” inside of one Program, with variations over both Presets.
• Much the same using one or two 3-way AUX switches, for external control instead of the onboard switches.
• The actual Performance destinations are specific to each algorithm & Preset location.  You’ll find parameters among these that can’t accessed anywhere else.

In your listed case, something like 1-BTN looping control in the Looper.  Depending on the delay algorithm, Repeat or Repeat (M) to freeze & loop whatever is currently in the delay buffer.
