DynaSinth / DynaSynth(new)
@Rob_Jackson_Music released what I feel is a banger addition to the "dyna" line of synth offerings.
SiNTh is fantastic for world building sounds and Synth is no different. It kinda reminds me of the sounds I use on the ARP or odd3ssi. It's very very good. Will post some videos later of some of the presets!

Really fun sounds! Enjoying it.

DynaSynth Dynamic Shape Synthesizer - Overview
DynaSynth is an original design based on variable shaped dual analog-flavoured oscillators for each of its 8 voices, that uses its own output to modulate parameters dynamically. This can produce interesting sonic results that would be very difficult, if not impossible to achieve using traditional fixed LFOs and envelopes. That's because:
As the sound changes, so does the modulation amount, which changes the sound, which affects the modulation amount...
Dynamic / Modulation & Display
At the top of the UI is a realtime display of "dynamics", wave shapes and all the modulation being applied. The (D) dynamics indicator is essentially an envelope follower with variable damping that is used as a modulation source for the oscillator shapes (1/2), vibrato (v) and filter (f) cutoff.
MIDI Implementation
DynaSynth is an 8 voice polyphonic velocity-sensitive MIDI instrument and is playable over a keyboard range from A0 (21) to C7 (96) on any MIDI channel. DynaSynth also responds to mod wheel, expression (CC#11), sustain (CC#64), channel aftertouch, all notes off (CC#123) and pitch-bend.
DynaSynth vs. DynaSinth
While they can be confusing, the names are very similar on purpose, representing a shared design theme, i.e. a synth that is dynamic. The DynaSynth design actually came first, and it is based on fairly traditional analog-flavoured oscillators. DynaSinth shares the same dynamics engine but with a modified set of parameters designed to complement the sound of its sine wave oscillators. While I like to think both synths have their own character, and can sound fairly unique, DynaSynth is probably more capable of producing familiar analog synth tones, and DynaSinth lends itself more to keys and pads. Both synths are also good for those who like to experiment with "out there" / "Sci-Fi" type sounds, and DynaSynth is probably better suited for that sort of thing.
Cheers, -Rob
Rob, another insta-purchase from me!
Hehe, I just had a funny thought (though it might just be me, and that my morning medication is kicking in) but you could probably release a new app and quietly charge $39.99 for it, and we’d all STILL insta-buy it!
I am getting the coolest presets from the randomizer. So unique, So fun.
Call this one clown orgy:

@egobeats - these demos of yours are fantastic!
Both synths are also good for those who like to experiment with "out there" / "Sci-Fi" type sounds, and DynaSynth is probably better suited for that sort of thing.
I think @egobeats has just provided solid evidence of this.
It compliments Continua very nicely when doing sci-fi atmospheres.
Worldbuilding with DynaSinth
There’s a problem with these videos of yours…
…they’re too short!
omg @Rob_Jackson_Music - now you're just trolling us with these app names. 😂
What's next DinahCynth?
@wim
Brace yourself for the next release... it's going to be DynaMite!
Don’t be giving him any ideas lol, epic trolling indeed 😅
I virtually never use randomizers ... except for in Rob's synths. All of them except AnalogyDM. I don't even stop by the preset tab, just hit randomize a few times until something great comes out, maybe tweak a thing or two, and I'm off to the races.
Doug’s video showcases it really well!
Fun info for PolyPipes users in that video… from Paul directly.
Oh man… Euclidans Randomizer w/ Robs Dyna s(I)ynths is incredible…
I think Euclidans randomizer is a special lil fella.. chords, repeats, program, scale, speed.
Highly suggest loading 4 instances fed by Euclidean using Euclidians randomizer.
Same process with multiple instances of AnalogyGr:
Prism's randomizer is no slouch either. I'm always surprised at how well it does on hi-hat patterns.
But, tbh, with those two exceptions, randomizers leave me with an empty feeling. I really don't like using them.
Prism has the best randomizer, i've ever used. Not sure why I find Euclidians so incredible. seeing the dials moving at different speeds/directions makes me happy.
re: high hat patterns...
i like running Poison 202's hat preset into Polypipes using the stutter patterns! so cool
Went to go check out the Sound Test Room video and someone else is doing it besides Doug. Kinda caught me by surprise
Edit
And now the video is gone and a different one is up now
Thanks @egobeats and @wim !
There's actually a little secret sauce in my randomizer code...
Some parameters will randomize over a certain range depending on the value of another parameter. Simple example being a low pass filter leaning more towards higher cutoff frequencies, and a high pass filter more towards lower frequencies. There's quite a bit of un-randomizing like this going on under the hood with all the latest synths.
General idea / hope is that you're more likely to end up with something useable. I think (personal opinion alert) that when you truly randomize every parameter, you end up with stuff that is more likely to be unusable or even inaudible. That's my issue with randomisers on some synths I've used, so I wanted to put my own random spin on that particular feature in my own instruments
it's really fun playing with it in OTOO, what a fun lil AU synth
@Rob_Jackson_Music
Hey, I just purchased Dynasynth... I thought I was purchasing Dynasinth.... I didn't realise there was a new thing.
I saw Doug at the sound test room had put up a new video about Dinasinth which reminded I wanted to buy it. Except it was actually about Dynasynth and I didn't notice the difference. waaahhhh.
Can anything be done to swap licence or something? Send me a PM if you prefer..., thank you
I bought both by mistake lol.
Good synth though.
Hi @JustinOllman - the developers don't have any control over that I'm afraid, so you'd need to request a refund from Apple directly.
Seems the most likely option is to select the "bought by mistake" option, which in this case, is exactly what happened.
Sorry I can't help more than that. -Rob
Dude just buy both, they’re only 3 bucks.
Isn’t DynaSynth basically DynaSinth but with way more features? I’d say @JustinOllman s problem isn’t a problem at all but a beautiful mistake. If you really wanted the other version just set some of the new parameters of DynaSynth to 0, no? Maybe I’m missing something…
Hmm... not really.
DynaSinth oscillators are sine waves, and has a set of features designed to compliment those sort of tones.
DynaSynth oscillators are virtual analog saw, triangle and pulse, and you can dynamically morph through the shapes (incl. PWM). DynaSynth also has a ladder filter with LPF, BPF and HPF modes which leans more towards traditional analog synth type sounds.
Hope that helps.
Sooooo not the same in the least? Haha! Apologies for the dense take, thanks for the clarification. Watching Doug’s video now, sounds rad! Another great addition to the Rob catalogue 👍
In New Zealand they're 6 bucks. Dude, you have no idea of my financial situation and I have a very tight budget for purchases of any amount. I specifically wanted Dynasinth as I heard some sounds in Doug's first video that were very close to a specific sound I really like but hadn't been able to find. So it's annoying to find I'd bought the wrong thing. And to be frank, annoying that the developer would have such a naming scheme in place that is sure to produce confusion. Maybe I should have been more careful, but how many times in the past have I had to be aware of 2 similar products from the same developer with one letter different that doesn't even change the pronunciation?
Edit. Lest I sound too ungrateful, I do acknowledge they are very cheap for what they are, and amazing value. So respect to the dev for that.
@JustinOllman my apologies. You’re totally right.
@JustinOllman - Why not try a refund as the developer suggested? That's the official way to handle it, and should theoretically work.
@Edward_Alexander
@wim I intend to, but last I tried it hadn't shown up in my purchases in the 'report a problem' or whatever it is. Seems to be a delay before recent purchases show up. Thanks all, its a minor thing really.
I forgot about the delay @JustinOllman. I think I've done the very few returns from the emailed invoice in the past, and you're right, they take some time to come. I hope it works out for ya. 👍🏼
