Audio Kit Digital D1 synth

March 10, 2019

Audio Kit did it again! D1 is a great iPad synth. This time it’s 80’s inspired.

After giving us (and I mean giving for free) SYNTH ONE, they now have an hybrid synth using PCM & Virtual analogue. It’s a 64 voices synth inspired by the 80’s and 90’s synth.

I really like it, and here is why!

What is “PCM” in the synth world.

PCM stands for Pulse Code Modulation. It is a type of digital encoding for audio files to keep a high audio quality with minimum memory space usage. Basically a PCM based synth is using audio samples (short digital audio recording) created by the maker of the synth. Some call these synth ROMPLER compare to SAMPLER. A SAMPLER can either record or import your audio samples as raw audio sources. The PCM Rompler were the most widely available synth technology of from mid 80’s to the end of the 90’s.
