No AUV3, forget it

This might have been good if they’d updated it to an AUV3 but unfortunately without that functionality it’s just a very dated looking UI with limited application.

Useful for multipart compositions

Update May 2023

Can you please answer this question.

QUESTION: How can we sustain a note instead of playing note to note.

I’ve sent emails and asked over a year ago.

Now your email doesn’t work.

========
I think this is a fantastic app for compositions. I can’t figure out, though, how to sustain a note. Is this possible? If not, can you add this feature.

Response from developer

Each step can have a duration (gate) of up to 400% of a step length - you can use that to create sustained notes.

Funktioniert nicht

Keiner meiner Synths Nave, iMini und Nave liess sich über den Quantum ansteuern. Ich hab an den Synths und Quantum alle möglichen Einstellungen ausprobiert. Nichts war zu hören!

Response from developer

Please contact me so I can help you with your setup. There is an email for support in the app.

More than a traditional step sequencer

I haven’t found an end to what this can do

Response from developer

Thank you for your review. Glad you are enjoying sequencing

Very complex..but ultimately brilliant

Update to my first review……I set Quantum up as described in my previous review, I removed all synths, then launched iM1 in track 1 and made sure it was set to Multi mode (inside the app), then pressed Play in Cubasis3 and WOW….notes and drums flying around everywhere, it sounded like a full orchestra practicing because I never expected to hear all the sequencer parts playing at the same time. The 8 part multitimbral iM1 is the perfect companion to Quantum Sequencer, now all 6 sequencer parts CAN be heard at the same time, it’s just fantastic, well…..it will be once I set the sequences to harmonise with each other.
Worthy of ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

Wed 20 July.
I have just purchased Quantum, I primarily wanted to use It in Cubasis3, and already I have spent what seemed like hours trying to get a sound out of it, all was lost until I opened Audiobus 3 and selected Quantum as Audio, then set Cubasis3 as out….success, but when I set up 3 synths in Cubasis, then create 3 separate step sequences in Q, only one of the 3 synths selected can be heard at a time!
A very complex and mind boggling app, and no doubt incredibly brilliant, definitely need to read the manual with this one though.

Thank you for your review - I'm glad you find this app creative

Amazing but struggling with a couple of things

This review is just a rough recording of my experience with the apps, devices or combination(s) of devices & apps mentioned, made mostly without any technical knowledge of them.

It would seem that because the QUANTUM iOS MIDI sequencer does not by itself emit audio and therefore does not advertise itself as an audio source to the AUDIOBUS device (AU or APP) list, it is not detectable (or not recognized OR BOTH) BY AUDIOBUS as an audio source and where AUDIOBUS only makes the device currently generating the i/o data of a sequence rather than its audio emitting recipient (MIDI slave synthesizer etc.) available as an audio source it is impossible to route audio from instruments sequenced with QUANTUM iOS MIDI sequencer to recording, looping, sampling apps or built-in sound library recorders (AudioShare, AudioCopy, Flip, AUM, GarageBand, Xequence) WITH AUDIOBUS internally in iOS. This is of course a non-issue if you plan to work with external devices to record, sample or just amplify audio generated by instruments sequenced with QUANTUM iOS MIDI sequencer.

Independent of this, Quantum is AMAZING. The device has far more options, features and flexibility than I MYSELF will ever need in an iOS device, but it would be idiotic to cite that as a negative! Especially fun for note by note, parameter-locking or “vertical,” tracker-style sequencing. Well worth the investment of time and revenue but I would recommend primarily as an iPad app. In fact, evaluate it using an iPad before passing final judgment.

Funktioniert nicht, iPad Air IOS 15

Der Sequencer läuft zwar aber die Gate-Länge aller Noten ist null. Auf Note-on folgt sofort Note-off, das bedeutet, dass kein Ton gespielt wird. Mit Midi-Monitor überprüft.

Problems with velocity send Signals

Sing the App to Control Software Synth on the IPad Workshop Great. But when sending MIDI to My Hardware Synth (Novation Peak) or Software Synth on my Mac (Arturia V Collection) the differences in velocity are not transported. The notes are equally loud or muted. I would have liked to ask this question by email but there is no possibility on the developers Web Site and I don`t wann to establish a Facebook Account to do so. So would you please answer how to solve this.
Thanks

It”s not monotonous!

This is my favourite iOS sequencer. It will run all my iOS synths and also hardware synths. It is comprehensive and a little bit of time spent on YouTube (The developers own channel or The Sound Test Rooms tutorial) and with the manual are worth it. It is a step sequencer, not a piano roll. I love it and I have purchased a few others over the years, but always come back to Quantum. I learn something new, every time I do.

Very Deep

This is one where you need to read the Manual. (Very well written).

I learned the hard way! Purchased it, tried it, got frustrated and pushed it to one side.

Thanks to this prolonged lockdown - I dusted off some of my - pushed aside apps and took a second look. Well worth it - this one is a gem.

There are a few ‘look see’ Videos on YouTube but nothing will beat hands on - keep it simple at first Just Quantum and you favourite Synth on the desktop no need to use a DAW - But works equally as well in one.

This app goes way beyond your standard sequencer. Way way beyond.

excellent midi sequencer

an excellent midi sequencer, super comprehensive feature set, very creative workflow opportunities

Was sooo excited till I tried it :(

Its fun for sequencing other ipad apps but I was really hoping it would also work with an OSX MIDI Network Session like ALL my other midi apps do. BUT IT DOESNT (crying) It has so much potential too! Ughhhhhh.... Dying

Its basically useless to me as its unable to touch hardware synths and VSTs via my Mac as I'd hoped. :(

Devs PLEEEEEEEASE fix!

Has its problems

As a sequencer the ideas in it are good - ratcheting etc. It works fine controlling an iOS synth.

The problems start when trying to get it to work with a DAW on a computer. The Ableton Link feature is implemented in an incredibly confused and confusing way and even when the app claims to be running using Link it sends no MIDI to anything, anywhere. Live 10’s transport doesn’t work when using Quantum with Link either, so even if Quantum did send MIDI there’s no way to record it.

All the other ways to connect MIDI from an iPad to a Mac (cable, wi-fi etc.) don’t seem to work either and usually result in Live’s transport not working for playback or record.

What “help” there is is incomplete and useless for problem solving. Several hours searching on line turn up other people with similar problems but no answers that actually work.

A waste of money? No, unless you want to use it with a DAW or hardware synths. Which unfortunately I do. A pity because on the face of things Quantum is pretty much exactly what a touch-interface step sequencer should be - if only it actually worked properly.

Lacking inter app audio support

What a shame. This app is amazing, and I really wanted to get stuck in. But I think until it works in apps like AUM and Ape Matrix, Cubasis etc, it is pretty limited to just a standalone app.

Are there any plans to make this IAA/AU3 compatible? I really hope so, otherwise I think I’ll be requesting a refund. Thanks.

AUM support PLEASE

This app is bananas... so deep and flexible. My only wish is for AUM support.

Anthony’s masterpiece

All of Anthony Saunders’ midi apps are the best in their genre, but this one is his masterpiece. It’s my go to app when it comes to creating bass lines and melodies, and if you’re doing Berlin School or any kind of dance music it’s a must have app.

It’s on offer at the moment, and so it’s a complete steal. It’s one of the few apps I couldn’t live without.

Excellent

Professional and deep. :)

A Great One

Very cool sequencer with a ton of features that work. The app is solid and reliable.MIDI is very well implemented. I wish all the developers would get together and implement MIDI in a consistent way. Quantum is one of the good ones but there are so many that seem to have implemented MIDI as an afterthought even in apps where MIDI is a vital part. Very strange. The sad thing is that the way it should be done is obvious to anyone who actually uses it. Quantum does things the right way.

Deeper than space

I am impressed with the potential of this app, and there is a lot to take in. It’s instantly fun to play with, although achieving something special will take a while. That said it is a journey worth making. Note, app support is via the little book icon at the top right.

Response from developer

Hi Nic, If you click on the picture of the book (top right of main screen) it takes you to a page that allows you to email me with bugs or enhancements. You can also access the 32 page manual there (or directly here http://www.amssoftware.org/manual/QuantumManual.pdf). The fb page is just for news.

Tangerine times 10

This is insanely good, with so many features that are just hiding in there waiting for you to understand. When I find a lil feature it makes me happy that this app dev digs the old school ways. It is way more than I thought at first.
