"My project based on Digispark - ATTiny 85 16MHz arduino programmable.

The main idea is that it's possible to use two PWM outputs for DDS. One of them will be the main wave generator, other will be the envelope shaper.

But I could't find any simple, but good VCA, utill i saw elektrouwe 7052A circuit in this topic: http://electro-music.com/forum/post-405863.html#405863

In MIDI interface you can use channels to tell ATTiny 85 what kind of waves to generate i.e. 1st channel - sine, 4th channel - square, 5th channel - white noise and so on.

Digispark (ATTiny 85) as USB MIDI interface & oscillator
TDA 7052A as VCA
561ЛН2 (CD4069UB) as state variable filter

via Digispark

"The Digispark is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE the Digispark is a great way to jump into electronics, or perfect for when an Arduino is too big or too much.

The Digispark is shipped fully assembled except for the two included and easy to solder headers.

Here are the specs:

Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
Power via USB or External Source - 5v or 7-35v (12v or less recommended, automatic selection)
On-board 500ma 5V Regulator
Built-in USB
6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)
8k Flash Memory (about 6k after bootloader)
I2C and SPI (vis USI)
PWM on 3 pins (more possible with Software PWM)
ADC on 4 pins
Power LED and Test/Status LED"
