SidTracker64 is the ultimate chiptune production package tool for the iPad. It emulates the SID sound chip from the dominating home computer of the 80s - The Commodore 64.

Get started immediately with the bundled songs and sounds in various styles, from old skool bleeps n blips to new school with multi speed and advanced table editing. Explore, remix and make new songs based on the old classic c64 game tracks “Commando” by Rob Hubbard or “Blood Money” by Fredrik Segerfalk, and the brand new youtube remix hit of the “True Survivor” Kung Fury soundtrack, all included in the app.

SidTracker64 is a retro-style music creation tool and synthesizer combined with modern features such as midi keyboard and controller input, Audiobus 2 and Inter App Audio for recording in your favourite DAW-app. Midi clock in lets you sync to other apps and hardware drum machines and synthesizers, such as the Elektron Analog Four.

SidTracker 64 can be used for live looping, making complete songs, and the minimum latency makes it suitable for live use. Export your music to Dropbox and e-mail as audio or .sid and even .prg files which you can run on a real Commodore 64.

Editing is based on hands on touch interaction or midi input instead of the hardcore style of direct data editing. Record live to a metronome or input notes step-style. Real SID-composing has never been simpler and more fun!

Fantastic music app

By far The Best SID tracker on iPad. May very well also be the only SID tracker on iPad, but that’s irrelevant - you don’t need anything else.

Great piece of software with fantastic sound and smooth UI.
Highly recommended!

I am so close to loving this app

As someone with an iPad Pro, I would love to give SidTracker 5 stars. I love how much potential this app has. For a tracker, it is very fun to use—but I find holding the 12” iPad in portrait mode while working to be a pain. If it was possible to toggle between portrait and landscape mode, then this app would be perfect.

Aside from that however, I have no complaints. This app is just what I’ve been looking for to produce chiptune songs, and probably the most learner-friendly tracker I’ve come across so far. Definitely a keeper!

Great app, but needs landscape display

This app succeeds at providing authentic C64 sounds and also provides a streamlined creation experience.

I have one major complaint: the app does not display horizontally / landscape mode on iPad Pro 12.9 inch displays. This makes composition on the touch screen impossible as you end up sliding the app window off screen or dragging the app bar or other windows over the already small piano keys.

To the developer: PLEASE add landscape display as soon as possible.
I ordered a $100+ midi keyboard to work around this.
