A complete workflow

I wish the core of those who wish to use this app could give bug fixes.
Well, the screen does not align for iPad Pro devices.

As from the bottom up has more screen but it conflicts with use ability a bit.

Now, on iPad Air it is in reverse the room from the top does not conflict with app. But u know screen size is missing but all the app still shows up good.

I hope I did help. Peace R.E.J. Singlecellsoftware!!!

I still love it

This app has all you need to start composing tracks or just put down rhythms for saving ideas. Special for younger musicians that want to start in the world of computer music and loop making.

Perfect if it appeared in files app

If the dev could make caustic visible in the files app users like me would pay 30 bucks a pop without blinking. Still working on 0S 18

FAQ

What is Caustic 3?

Caustic 3 is a mobile music creation tool that emulates rack-mount synthesizer and sampler rigs. It allows users to build their own virtual studio by adding up to 14 different machines, including various synthesizers and a drum machine. The app is designed for real-time audio production and is optimized for mobile devices.

What kind of synthesizers and machines are available?

Caustic 3 offers a wide variety of machines, including a Subsynth (virtual analog), PCMSynth (multi-sample), BassLine (303-like), BeatBox (8-channel sampler), PadSynth, 8BitSynth, Modular, Organ, Vocoder, FMSynth, KSSynth, and SawSynth. Users can combine up to 14 of these machines to create their unique sound.

Does Caustic 3 support external audio input/output?

Yes, Caustic 3 supports AudioBus for both input and output slots, allowing integration with other audio applications. It also supports AudioCopy Paste and AudioShare for easy import and export of audio files.

Can I import my own sounds into Caustic 3?

Absolutely. You can record your own WAV files directly within the app for use in the PCMSynth, BeatBox, and Vocoder. Additionally, files can be imported through iTunes file sharing, ACP, AudioShare, or the built-in FTP server. The PCMSynth also supports SoundFont (.sf2), SFZ, and FL/Xewton instrument files.

Is there a free version of Caustic 3?

While Caustic 3 itself is a paid application, there is a free, full-featured PC/Mac version available for download on the product website. This allows users to explore the capabilities of the software on their desktop before potentially purchasing the mobile version.
