Studio Session is a 1986 software program for Macintosh computers, for music creation and playback. It was created by Macintosh and Newton pioneer Steve Capps and musician Ed Bogas. The program was published by Impulse, Inc..
The software differed from other audio creation packages as it used 8-bit audio samples of real instruments rather than sounds generated by the Macintosh sound chip, as did packages such as MusicWorks and Deluxe Music Construction Set (DMCS). It was capable of playing back 6 tracks simultaneously in the original version, updated later to 8. There were two modes or screens, the authoring screen and the playback-only screen. In the authoring screen, the user entered notes on a staff with treble and bass clef using the mouse, and selecting the duration of the note with on-screen buttons or keyboard shortcuts. In the playback screen, an animated simulation of a VU-meter was displayed for each track.
The package shipped with a selection of several sampled instruments and several add-on packages were later released, such as the Heavy Metal Instrument pack that included more drum and guitar samples. Other packs were Country and Brass.
The music samples provided were created by Gary Clayton working with Ed Bogas' band. The user was not provided with any software for creating their own instruments for use in Studio Session, however it was possible to record new instruments or convert existing samples using commercially available audio-editing software such as SoundWave from Impulse Inc with the MacNifty Audio Digitzer.

Reception
Compute! called Jam Session "a strange, entrancing thrill", stating that it was harder to use than Instant Music but provided more control. It won the 1987 Software Publishing Association awards for Best Graphics and Best Entertainment Program.
New version
In 1989 Broderbund released a new Jam Session version for the Macintosh II and SE computers as well as the Apple IIGS computer, differing in its utilization of full color graphics for animated performance scenes and 15 voice stereo music. Musical themes featured in this port were: Pop Rock, Heavy Metal, Country, Classical Concert Hip-Hop, Rap and Jazz. Users loaded a song from a specific theme and simply "jammed" along using the keyboard to play accompanying instruments, which had the option of being auto-harmonized and auto-timed to match with the musical score playing.
