APM Tool is a new utility to analyze the acoustic properties of a room, so you can decide if and how you want to treat a room.
APM Tool iTunes Description:
With APM Tool you can measure the acoustical performance of a room (reverberation time, clarity, etc.), check if that room is well suited for your purpose and, if not, choose which materials can improve the acoustical behavior.
You can also, save, load and export results in common spreadsheet format.
A tutorial slideshow explains the app usage.
In the last several years, all of Korg's little hardware synths have been built to be hacker friendly. They even go so far as to release schematics for encouraging circuit exploration, allowing the community expand and improve upon the capabilities of their hardware. MATRIXSYNTH found this example from Alessandro Fasan, who worked out how to control the non-MIDI Monotron Duo from an iPad!
I wanted to share how I MIDI-fied my Monotron Duo from Korg. The TeensyDuino 3.1 controls a dual DAC and a dual digital potentiometer. Many thanks to Marc Nostromo for inspiring this design. I plan to share the SW with Marc Nostromo's blog, what I came up with is based on the code that he originally posted in his blog (it was for the regular Monotron).
The challenge with the Monotron Duo is that it requires two voltage controls (one for the ribbon, one for the octave), so it required some reverse-engineering from the schematics that Korg kindly made available.
I wanted to design a pad sound and turned to Cassini for the task. This is a bit of an unsung app, not getting nearly the amount of attention I feel it deserves, so I made a Let's Play out of it! Here I talk through the whole patch design process. This is the first video sponsored by Patreon, so a big thank you to everyone who has supported me in this new series!
Cassini is one of my favorite synths on iOS for its ludicrous amount of modulation envelopes. I like to turn to it when I need a pad synth patch, and today I need a dark rich pad! If you enjoy these Let's Play videos please consider sponsoring them on Patreon: http://www.patreon.com/user?u=107612
Reader ZenLizard, a contributor over at SynthPatcher, did a Quick Start guide to DrumPerfect. He provides excellent explanations for some of the complexities in the app, while making it look and sound fun!
