Hydrasynth from ASM - Tips, Tricks and Queries

So, in fact I had an outdated manual and firmware. So here’s the possibly most simple option with FW 2.0.0 :

  • Use a stepped LFO in semitone mode with 2 values : 0 and +12.
  • Trigger mode : one-shot step
  • Voice StMode : RDM

It’s a bit confusing that the StMode which refers only to the Panning (“St” as “stereo”, right ?) in fact refers to the voice allocation itself.

Yeah a voice is the combination of the 3 oscillators and noise going through the filter then Amp.

Panning individual oscillators is found in the Mixer menu.

Two Filters, each with a wide range of selectable filter types, that can be arranged in series or in parallel, with a large range of possibilities on arrangements on what inputs goes to which filter in the mixer. This all has a large range of variable control by the Mod Matrix outputs.

It’s really worth closely investigating this and the modulatable output controls to filters and mixer in the Mod Matrix.

Oh yeah, you can get some cool stereo filter patches when panning oscillators and then having them go to specific filters.

I wish Filter 2 was an exact replica of filter 1 though with all the modes you can select…

Indeed. Saving the second filter for last provides tons of easy to reach sound shaping. A very small amount of audio rate modulation of a tiny bump of resonance goes a long way.

Same! The Multi/Poly has that and it’s wonderful.

Yeah it doesn’t make sense to me.
Like… does it take more processing power to have all the modes available for both?

Does filter 1 take more processing power than 2 or vice versa?

By and large the default filter 1 sounds pretty close to filter 2 anyways, if not identical, but would have been nice to do twin LPGs and stuff

I played around with this a little and it (obviously?) refers to poly mode only. In mono mode (polyphony in the voice menu) you get predicable results from the step sequencers, but interesting things happen in poly mode. I’m still trying to work out how StMode interferes with the steps exactly, but it’s interesting to play around with the various modes. I wonder if voice stealing becomes part of it so you could have some voices with longer envelopes interfere with the steps too… Great find!

Crossposting this, as it looks like a nice editor.

Binaural Patches on Hydrasynths

This is a nice tip, from Loopop.

You can set up binaural patches pretty easily on the Deluxe of course. You also can do it on the other three with this tip.

Make the same choice ( or something very very similar ) for each of the two primary oscillotors and then in the mixer pan one hard left and the other hard right. Then use the two filters in parallel. This gives you effectively now four filters. Plus the mutants can be set up separately per primary oscillator.

See Loopops video on the Hydrasynth vs The World :

Stay tuned after that for a cool part about using the Hydrasynth Randomizations, particularly setting up randomization percentages.

There are other fun randomization tricks too, that he does not cover in this video, but have been talked about elsewhere in this forum, as well as many other places.

:thinking: I’d rather say 2 stereo filters…

I wish we could randomize OSCs without changing pitch.

Yes.

Queries from a newcomer with an HSDR:

  • Has ASM given any indication that it can address the problem of silencing of a patch when it is saved?
  • Is there really no way to save another set of System Setup values other than to backup the entire memory to computer and recall another backup? Given the versatility of configuration of the unit (and enough capacity for 1024 patch memories), I have been frustrated by this within two days of buying. Did anybody ever request this?

Edited to reflect that there is no way to save another set of System Setup values.

No way for both points AFAIK…

Hi Peter,

I had been preparing a response. It doesn’t go very far beyond what sezare56 says already though.

As to the first part, the silence that you get when saving … my recollection ( a foggy one ) is this has been attributed to a hardware design issue, rather akin to the relative slower rates of saving / loading of patches. I think it may relate to the process involved with storing to non-volatile memory. ( For example : needing to pull a bus away. )

The second part ( about being able to save alternative system setups ) is ( to me ) a more interesting problem.

Your approach is to my knowledge the only way to work 'round this problem. I am not aware of any SYSEX or NRPN that makes system changes, apart from some very limited changes with NRPNs, like changing the source for CV gate, between keyboard and ribbon, turning overflow on and off, and changing some of the aftertouch parameters.

I first tried to think of other hardware synths that have approaches to handle this need. Elektron has some of this, being able to store some “working states” in projects.

But what i was looking for was hardware synths, that allows you to have separate users, ( USER1, USER2, USER3, … ) with separate system setups, like on a computer, and a way to go between “users”. I couldn’t really think of one. ( Did the Korg OASYS have this, i can’t recall for sure, it might have ? )

So another way this gets approached is for companies to pull system parameters into patches. A prominent one i thought of, is a Behringer firmware upgrade, making the really extensive vintage “atrophy profiles” on the UB-Xa, part of every patch, instead of a system setting. The atrophies can have really extreme affects on the sound, so it makes sense to have them part of a patch. But that doesn’t cover the situations where you want to have two independently variable groups of stored parameters.

As far as ASM doing this with a HS, i thought one place to look at possible future options for this was on the LS. But the implementation there, for this sort of thing, is pretty much the same as on the HS.

The Diosynth, with a different focus on use, does have a few parameters that can be either global or patch settings like scale and tuning.

So like i said i don’t have too much to add. I think you might want to consult with either Ken ( @Flux302 ) or Glen ( @GDarcey ) to see what they may have to add.

Thanks for your thoughts.

The silence on saving is a minor inconvenience, probably based on my experience with other instruments. I can just wait to stop playing before saving.

It would be very useful (for me, at least) to be able to save more than one set of System Setup values on the HS itself. If that were too difficult to add, it would also be useful to save a Setup via the Manager software and/or send a SysEx file to a computer for later recall.

Many manufacturers (in alphabetical order in my collection DSI, Elektron, Emu …) provide the capability to dump and recall information other than just patches by SysEx.

I will at least submit something to ASM via their Support page.

Bit of a random question, but does anybody know if the Hydrasynth desktop units have a midi panic key combo or button?

I’d like to start exploring mine again, but I like to identify that before delving and I cannot find anything in the manual.

Finally found it. Was looking for “midi panic” or “panic” in the manual.

All Notes Off
Sometimes MIDI signals are disrupted and
a note becomes stuck. If that happens, hold
[SHIFT] and press [HOME] to transmit an “All
Notes Off” command. This will silence any
stuck notes.

Midi panic at home ! :scream:
