StepPolyArp

This is an amazing app that lets you create and play arpeggios or sequences with ease. It is very well thought out. I use it to play Korg synths via Korg Gadget, and to create a complex or simple backing through a Korg Pa arranger. You should have a basic understanding of midi if you want to drive internal or external synths. Also, basic music theory is helpful for understanding scales, etc.

The gating and improved UI and random features are very good. Would be interesting to see some of the features like Omnisphere’s arp has on desktop, or warping features to play with time. I bought chordpolypad as sort of a tip for your updates not thinking I needed it, but found it works well with StepPolyArp.

Versatile

This is an excellent arpeggiator! Unfortunately I see no way to use the velocities that are played on the controller versus translating them to the sequence of velocities stored with the arp pattern. Is there a way to bypass the velocities so that you can utilize your own performed dynamics like the way most hardware arpeggiators work?

The functionality it’s there, but is there a way to add a sampling feature. Just to add different sounds and not just stock sounds. Just an idea

Love this app but I am finding myself wishing it had some realtime velocity control when I am playing chords into it. Would love to see capability in the next update. Thanks.

GOOD and EXCELLENT: ***Excellent stability, does not crash. ***Great overall control of the pattern / arpeggio. ***Well designed user interface. ***Excellent velocity adjustment panel with multi touch drawing feature. ***Very useful “beat sync phase” under tempo adjustments. NOT SO GOOD: ***No multi select for events/notes (only in the form of selecting all, every other, every fourth etc. but not specifically selected notes). This forces tedious event behavior adjustments which have to be done one by one on every event (in addition the boxes in the menu for selecting the events behavior are small). ***The individual rows can’t have pitches loaded as a preset (meaning you can’t quickly assign a scale to all rows’ pitches. ). ***No quick global transposition. Yes, you could transpose the pattern simply by pressing a different piano key but sometimes you want specific keys to be pressed (when using piano keys to base the arpeggio on), also you can transpose pitch of each row in the pattern individually but you can’t quickly do it to all the rows globally. ***Poor internal sounds, no user sounds. ***Confusing currently playing pattern indication (or a bug?). It’s the pattern that is due/next that is flashing, all other patterns are still. It would be easier to spot the current pattern if it was flashing or if there was another indication of the current pattern, such as display of the pattern’s number. ***“Grid edit” under the cog wheel in the top right corner above the pattern window not logical. Some controls apply to all the grid’s rows but “fill all steps” applies only to the main middle row. In addition, selecting “fill all steps” deletes all events in the other rows. ***Has a bug where sometimes changing the rows’ length has no effect on where the rows loop. ***After being opened in a background in a while as idle, when returning to the app it won’t plat the pattern / arp at all. A restart is needed (at least it remembers the state before the restart). *** Way overpriced

Extremely well made, well thought out app for arpeggios and sequences. This thing handles the bread and butter while opening up possibilities I hadn't even thought of. Also, I had a support question and the response from the developer was really quick. You get what you pay for folks, and this one's well worth it.

I love sound design and mixing, but I am not a musician. By using midi song kits I have been able to find new arrangements to mix, but it can be an expensive endeavor. This app, along with Odesi (for chords, bass, and drum midi), let’s me generate pitch perfect midi tracks in seconds, which I can then voice with the synth of my choice and mix to taste in Cubasis. Thank you to the dev! 🙏🏾

Capable of doing just about anything you can think of. Integrates perfectly with Cubasis. There’s a bit of a learning curve to climb, but the results are worth it. Make sure to read the manual. Tech support is very quick via email from the author of the software.
