MultitrackStudio has been designed to run very efficiently, so computer requirements are fairly modest. Some performance issues are discussed in the following sections. With newer computers the sound device usually is the only thing to worry about.
Windows: The 64-bit version works with the 64-bit versions of Windows 10/8/7/Vista. The 32-bit version of MultitrackStudio can be used on any computer that runs Windows 10/8/7/Vista/XP, including the 64-bit versions of Windows 10/8/7/Vista/XP.
Mac: MultitrackStudio works with macOS 10.14/13/12 and OS X 10.11/10/9.
At minimum, a 16 bit/44.1kHz/stereo sound device capable of full-duplex operation (ie., simultaneous playback and recording) is needed for audio recording/playback. Virtually any modern device will be capable of this.
On Windows XP Soft Monitoring requires an ASIO driver, and it's highly recommended for recording software MIDI instruments as well (latency will be much too high with the Windows XP audio driver type).
Real time audio processing requires a fast processor. MultitrackStudio is very efficient, so any computer in use today should be fine. You need a faster computer if you want to use higher sample rates like 96 or 192 kHz (Pro edition).
MultitrackStudio takes advantage of multiple core CPUs (up to eight CPUs can be used).
32 bits Windows version: features that use audio pitch shifting are only available if the CPU supports SSE2. SSE2 was introduced in 2000, so virtually every computer in use today supports this.
MultitrackStudio's memory requirements are very modest, unless you're using very large sampler patches.
Note that some sample based VSTi plugins can use lots of memory, if you use a lot of those then having 2 or 3 GB of memory is a good idea.
If your songs contain about ten audio tracks a fast hard disk (7200 RPM as opposed to the once standard 5400 RPM) is recommended.
You may need some special wires to connect microphones etc. to your sound device, especially if you have a cheaper sound device which typically use 3.5mm jack plugs, whereas microphones use XLR connectors or 6.3mm jack plugs.
Using an external high-quality mic preamp can significantly improve the sound quality of your recordings. They usually provide Phantom Power as well, so you can use condenser mics.
An analog compressor can reduce the risk of overloading the sound device's input. It also allows you to get more out of a 16 bit sound device's resolution.
Not all stereo sound devices allow you to set different recording levels for left and right channels. This can be quite a problem if you want to record two tracks at the same time (for instance a vocal track and an electric guitar track). You can solve this problem by using two mic preamps (that have a level control). Using a small analog mixer may be a cheaper alternative.
