I recently created this thread:

https://gearspace.com/board/electron...ml#post5745326

In which to share patches for DSI synths.

The intention with that thread was to keep it free from chat so it can remain uncluttered. However, someone else has just posted comments in there, and I empathise entirely as I want to shout about how incredible Ctrlrshft's patches are that he just shared!

So, the intention of this thread is:

* Discussion about that other thread, and the patches posted there.
* General discussion about sound design in DSI synths... share tips & ask questions.

Question number one:

Do we need some legal mumbo jumbo in that thread re copyright... or is this not an issue with patch design?

ie if I use someone else's patch that they posted in a song I make, can they turn around in 5 years time and claim royalties?

... Do I need to write something like 'by posting your patches here you agree to release all copyright blah blahdy blah....' or is that not an issue with synth patches?

If it is an issue... how should it be worded?

Cheers.

@ Ctrlshft

Utmost kudos on these patches:

... you just added SO much value to my new purchase :-)

Super-fricking-awesome!!!

Question number two:

On the Tetra page at the DSI website

Tetra Multitimbral Analog Poly Synthesizer. Specifications.

It states that there is one filter per voice.

I've taken that to mean that there are four filters... is that correct, or have I misunderstood this?

I have so far only utilised one filter AFAIK, but it appears (I haven't tried yet) that there is one filter on each of the A/B sections.

Do I need to be in Combo mode to access all 4 filters?

Next question:

On the Tetra, can the 'Sequencer' be used as an arpeggiator? ie so that when I trigger & hold one note, it will play a pattern based around that note?

I know I can always program an arp, or use a midi plug-in to create this data in realtime... but I just wondered if it can be done in the Tetra's Sequencer?
This would be handy for faking 'delay' into patches also.

It seems to me personally that this arp type of thing would be infinitely more useful (esp if it could be assigned to effects too!) than a regular Sequencer.

What uses are people putting this sequencer to? Is it just for live performance?

Nearly every polyphonic synthesizer has one filter per voice, as well as all other synthesis elements like VCA, envelopes, lfos. Everything is per voice.

Lets say you have a sound with low cutoff, low sustain, but a high filter envelope amount: As soon as you play and hold a note, the envelope opens the filter, then during the decay phase of the envelope, the filter closes again until you hear nothing anymore. Now you play and hold a second note/voice. If it went through the same filter like the first note, you would hear nothing because the first filter is already closed again. Or if the 2nd note triggered the first filter again, also the first note would sweep again though it should stay in sustain phase.

And yes, a VA like the Virus with 64 voices or so has 64 filters

I made a full sound bank w/ audio demo for the Prophet '08 and Tetra. It can work on a MoPho but you need to load it into a Tetra and then to a Mopho. Link is in my sig.

Hope this works.. can anyone test? Here's a .mid file which should contain may CS80 guitar preset for P08, hopefully.

Demo

Hey,

Patch sounds cool in the demo thumbsup

... But I've no idea how I'm supposed to get a .mid file to open as a patch... how are you using this?

The place where we are sharing patches is here:
https://gearspace.com/board/electron...ml#post5745326

... and so far, we've been sharing .syx or .t4p files which can be loaded via the Tetra's software editor.

Ah ok looks like i was in the wrong thread.. lol.

You should be able to throw the mid file in a sequencer and just play it, that's all..

Midiox doesn't seem to work for me too well, and i don't have the pro version of the soundtower editor (who needs that with a P08 anyway?), so i'm just dumping my patches the old fashioned way.

... so you simply 'play' the midi file as though it were notes... and this sends the patch to the synth?... presumably sysex within the midi file?

... sorry; I'm new to all this outboard stuff!!

I don't have the tetra fired up at the mo... but I'll try later.

Can you re-post that patch into the correct thread?... You might need to create a new zip file & rename it to trick this site into allowing a re-upload of the attachment... it seems to recognise & disallow things already upped.

The site seems to look beyond the filename, and it won't let me post it elsewhere.. maybe a mod can move the post?

How about if you re-pack the .zip file, only this time include an open source image of a smilie face or something... just so the .zip becomes totally different.

@Payt... nice one for reposting heh

Cool patch, will give it a try when I get some time.

Posted a few new patches up, woopwoop.

Digging this, I hope some more people contribute!

Yeah, this is really great. I promise I will upload some patches soon (read: eventually)- school just started up again and I'm crunched for time.

Good skills man. 'Exterminator' is especially lovely!!!

... Yeah- C'mon people. A little more early support would be great to give this a bit of a push.

I feel like a bit of a dufus asking to make this a sticky just yet when it currently just looks like a couple of crazy people on their own!!

i have a lot of patches for my evolvers.. mostly techno style, but some crazyness also. i had one in prison for over a year(my mother smuggled it in) so i used it for about 5hours aday for six month until the guards found itdfegad

ok i try making a dump, first time on PC, only mac before..

Thanks for pitching in, Corris! Rounder sounds like it'd be at home in a dubstep or d'n'b track in no time.

Yes, I made that patch actually for a kind of deep experimental Dubstep track! Watercoloring is one of the best padsounds I've ever heard on the TETR4..... thanks for that one

@Simonator
Your Tech-Stab-Sound is quite nice too!

Some more patches will follow!

Hey Corris, nice one for getting involved thumbsup

I reckon that 'Iron Lead' could be all you needed to make an electro house smash-hit if that was your intention.

Nice patches.

+1... Watercoloring is so beautiful & emotive. It's definitely one of the best sounds I've heard from the Tetra FULL-STOP.

Thanks for the kind words folks, glad you're enjoying that one as much as I have.

In other news, it you didn't already know, guess what came out on August 20th:

Tetra - Dave Smith Instrument

Just found out like 5 minutes ago. Annoyingly there aren't any release notes, and the update is only for the Pro version for some reason, (worth the green, despite reported issues btw, also you get the vst editor for free when it comes out) downloading now and will report back about any new findings.

EDIT: As far as I can tell there is ZERO difference in the feature set. AND THE SAME F!CKING LAYER B BUG EXISTS. WTF dfegadSOUNDTOWER?

Also worth noting that only the PC (.exe) version has reached 1.1.0.
The mac (.dmg) version is still on 1.0.3.


For some reason.

Sure enough, weird. I wonder if this was a goof or something. There's not even any mention of "slew" in the seq, which was part of the updates going around for the other stuff. I'll wait a bit but damn I am annoyed that I have to press Edit B everytime I want to switch to editing something on the B Layer if I want realtime editing. If it can't be implemented due to a firmware thing, fine, but SAY that.

C'mon then Jb... you going to share your 'tetradrift' patch with us then or what???
heh

thumbsupthumbsup

Thanks Bartman!

Fantastic patches! Good skills!

I've been digging a little deeper into the patch design today, but I've still not figured out one major thing:


If I've got a patch on two layers, how do I adjust filter cutoff on both simultaneously???

The 'cutoff' knob on the hardware only seems to affect the currently selected layer. Same issue with the 'assignable parameters'.

In fact, as far as I can tell, the 'assignable parameters' will only affect the currently selected layer on the hardware... how on earth do I make it so I can control the whole patch, this doesn't make sense.

HELP!!!

Thanks! thumbsup
There's one more on the way soon.

Unfortunately I don't think this can be done on the TETRA's front panel itself. You can always control filter cutoff on layer A and B simultaneously from an external controller however. One way would be to send CC changes on 15 and 215 simultaneously (from a DAW or Max/MSP etc), or you could just assign the mod wheel to filter frequency on both layer A and B for easy keyboard control.

Now that you bring this up though it is kind of annoying that it can't be done with the assignable parameters at least. A potential workaround I can think of is to make a combo instead -the default behavior for combos is for the knobs to control each voice simultaneously.

Thanks for your reply.

That is REALLY annoying.

Okay

I need to read up on Combos... haven't even started with those yet!
