## What is SynthStamp?

The Vintage Synth Playground You Can Take Anywhere

SynthStamp is a celebration of the history of electronic music, featuring fully modeled engines and familiar user interfaces behind some of the most desirable synthesizers. Tap and drag to patch, save your patch as a preset, and export presets to share across all of your devices including Mac, iPhone, and iPad. Yes that's right, iPhone. Take your sound anywhere.

Stereo audio input for realtime effects processing

Model based on the ARP 2600--finally on mobile

Circuit-bendable model based on the SK-1--we haven't seen one either

Choose Your Adventure

5001 Analog Synthesizer: dynamically patchable, semi-modular, monophonic analog synthesizer from the late '70s, with stereo preamplifier. A real idea factory, from classic analog synth leads to creative sound design, this synth is a tool for exploration and experimentation. You'll truly fall in love with the snappy, milky quality of the voltage-controlled filter.

B500 Sampling Keyboard: circuit-bendable ROMpler from the mid '80s, with 4-voice polyphony, multi-channel note memory, and stereo sampler. Bend, sample, and compose melodies with this portable gem. Combine with continuous live sampling to create sounds that simply shouldn't exist.

Flexibly Configurable, Infinitely Creative

SynthStamp can be run as a standalone application or as an Audio Unit (AUv3) plugin inside supported DAWs, either as an Instrument with mono side chain input, or as a Music Effect on stereo/mono audio tracks for realtime processing, with full MIDI support. Presets can be imported and exported for easy sharing across devices, while on the same device, presets are stored in a common location across standalone and Audio Unit installations for shared access.

### 4/5 — Could Be Amazing

*2026-04-24*

The concept is there, but the UI need some work. It said that in the instructions there’s a scroll bar on iPhone, but it doesn’t exist. You can’t really use it on an iPhone. I would gather it. It’s tight on an iPad mini too. On an iPad it’s a bit better and on a Mac it certainly the best. I’m not quite sure why both the keyboard and the synth images don’t default to larger in the first place.

### 5/5 — Insane space fusion of 2 synths

*2026-04-12*

Holding up the retro synth inspiration . The 2600 is certainly retro sounding, but really nice. The only crucial thing is to tame that reverb a bit and it’s ace. Perhaps that’s the way the old one sounded but as of right now (April 2o26) it’s just real dense and is maybe overpowering? It’s big and great for drones of course so that is cool. But to me the synth sound shines though with way lighter reverb or much less. Ok so the Midi in AuM is great so far. Pretty big deal. I have not tried midi learn yet. 
Updates are well done and it’s pretty much a dream. So fat it just keeps improving, and is a gift from an alien drop pod which is so cheap I thought it was April fools. Nope, it’s real and no IAP even! The other completely amazing thing is the prescription strength circuit bending. You basically get access to the virtual chip and the bends are appear legit (1st I’ve ever seen.)! It of course depends, as typically a bender used sliders/knobs. That would be quite inspiring, but it’s beyond complex as is. Yet understandable in a strange electric vortex of options seeming infinite even with robotic assistance. In general both synths have a nice quality of sound and are quite wild , almost in headphones you may blow up the universe or brain so maybe ‘ponder’ a limiter or compressor.
I like when the inspired retro gear/apps pushes the way into new tones. I think a lot realize it won’t be a clone sonically but the graphics can make it seem that way.
This sounds unique as well, with functionality quite close(without inspection A\B)! Seems like this came from the drop from portal zel along
hyperspace. I’m feeling like a double neck giraffe that woke up with wings. And the app of course.
Much appreciated and the work must have been done out of passion because I’ve honestly you could have charged way more, and made 2 separate ones. Cheers, the only idea I got is an iap of almost anything with custom graphic or knob/sliders.

### 3/5 — Great App! but…

*2026-04-11*

This is my first ever review, so this should say something. Fairly new to the ios music making world, but been diving deep. Out of all the synths and music utility apps and daws and auv3, this one has the smallest font. I saw this talked about for a few days in different forum destinations and I heeded the warning but oh, god how right they all were.

The synths sound great, I actually would like to play with them and use them and incorporate into my workflow as I can, but truly impossible with not being able to read anything I’m doing.

I’ve screen all three keyboards, the two in the mod and the toy sampler so I do have an idea now about what all the buttons are but that doesn’t help when in the moment of crafting a sound and trying to find with patch is going to connect to which output.

I truly want to like this app, and I do, like this app but I don’t think any of us can actually use this app until this feature gets figured out. Maybe with an actual zoom feature in app that let’s you scroll  very far into the keys and does so smoothly. Or the devs can figure out a way to enlarge the font without sacrificing the intent they were going for in the vision of the app.

This is all coming from someone who has great eyesight, and accessibility zoom feature on, screens shots taken while zoomed in. It shouldn’t be this hard to read the work flow, even at the fiver price point. Small knobs I can do, most apps are featured with that, but small font to the point of unreadable is kind of impossible though, impressive coming from someone with equally small handwriting ;)

iphone - updated to most recent ios - 3.5 stars until this gets sorted.

Other than that, it’s a great sounding synth with fun features and I would like to use them.

### 2/5 — On y croit

*2026-04-10*

Ce synthétiseur pourrait être bien, mais là il est illisible, donc quasiment inutilisable, même sur un iPad 13 pouces. Dommage. Il faudrait agrandir le synthétiseur ou au moins pouvoir zoomer n’importe où

### 2/5 — A good synth…

*2026-04-10*

…that the devs have made a terrible UI for…
Don’t buy it unless they fix it, so much wasted space, a tiny unplayable keyboard, maddeningly fiddly for no reason..
Hopefully they fix, it could be good, but at the moment it isn’t really useable..
Such a shame…

### 5/5 — Arp 2600!

*2026-04-09*

This came from out of hyperspace and dropped a synthetic alien (arp 2600) into portable use. Pretty big deal. Ok, so from the start Its hard to tell how authentic the sound quality is compared to the many hardware versions .I don’t think it has to sound exactly alike, but I hope the patch-points and functions are close enough. So, besides some small quirks/issues, they update and fix it often. I think can only Get better and better as they appear to listen to feedback as well!This is working well at this point, and midi was rolling through AUM great. This is a dream in my world, and I haven’t event touched the other keyboard. Cheers!

### 4/5 — Update

*2026-04-08*

The update introduced a zoom for the interface, it is now usable enough for me .

### 5/5 — Freeze issue fixed

*2026-04-08*

iPhone 8. When selecting the preset tab, app freezes. It’s now impossible to select the other instrument. I’d consider this app broken as is. Hopefully I can update my review to reflect a more positive experience. 

Side note: The 2600 sounds good. I can’t access the SK1. Also, a pinch zoom is preferable to the slider/joystick combo, but I can tolerate it just because I’m so excited to see a 2600 on iOS.

Update: The developer addressed the issue in a matter of days. This app is definitely worth investing some time in now. It feels like a fun little sound design lab. I’m starting to get used to the zoom/joystick navigation. The whole experience is very methodical. I like it.

### 1/5 — ATTENTION: Publicité mensongère.

*2026-04-07*

À part un menu déroulant vous permettant de choisir parmi 100 presets, absolument rien d’un  patch n’est paramétrable sauf le nom du patch. 
Aucun accès au moindre potentiomètre ou au câblage. C’est un rumpler primitif sans aucun intérêt, sans aucun paramétrage et au descriptif trompeur. 
La présence de ce logiciel à la vente est une honte. Je demande le remboursement. 
Ne vous faites pas avoir.

### 1/5 — Bugs avec les presets !

*2026-04-06*

Comment changer de packs de presets, le menu des presets ne répond pas ! Pouvez-vous le mettre à jour svp ? Le son n’est pas mauvais mais l’ergonomie générale est sérieusement à revoir !
