## What is SidTracker64?

"If you're into chiptunes, this app is a no-brainer" - iOSMars
"Drop everything and download: SidTracker64" - Stuff magazine

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!

### 5/5 — Great!

*2026-07-26, version 1.0.5*

It’s wonderful! The tools are familiar, the Arpeggio tool is INCREDIBLE, & I just *love* Recreating my favorite Game Soundtracks in it! And it would be just Wonderful if you could add a skin for the keyboard that makes it look like the “Incredible Musical Keyboard”!

### 3/5 — Good app, but drains the battery

*2024-12-25, version 1.0.5*

The app is quite good and easy to use. I have only a small and a big issue with it, hence the 3 stars:
- it only works in portrait mode on the 12,9” iPad Pro, which makes it a bit cumbersome with the folio cover. The piano keyboard would also benefit from a landscape mode.
- the bigger issue is that it constantly runs in the background, depleting the battery in 1-1.5 days when the iPad is not used.

### 3/5 — Updates missing!

*2023-09-30, version 1.0.5*

Good app. but not a single update in years. Doesn’t emulate 6510 Sid chip.

### 5/5 — I retract my criticism.

*2023-03-23, version 1.0.5*

It does appear to be feature complete. Good job.

### 5/5 — Excellent tracker

*2022-10-09, version 1.0.5*

Love this, everything is done right. Great UI, great emulation, great export options.

### 4/5 — Great app, but needs landscape display

*2022-07-24, version 1.0.5*

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.

### 4/5 — Landscape View Support for 12.9 Pro away from perfect

*2022-03-30, version 1.0.5*

It needs to support landscape view.

### 5/5 — Horizontal mode required for 12.9"

*2021-12-14, version 1.0.5*

SidTracker64 is great. On 10.5" it works horizontally (OK), but on 12.9" it work only vertically. Can I request an update to correct this, to tracker work horizontally also on 12.9"? Thank you in advance. Kind regards.

### 4/5 — Please add horizontal 12.9 support

*2021-11-24, version 1.0.5*

Great app but please add horizontal landscape support for 12.9 inch iPads. Too awkward to use in portrait mode!

### 5/5 — This is awesome

*2021-10-25, version 1.0.5*

would be neet if you where about to import sid files from the file app then could use it as a sid player too
