a) new audio demo of AudioEngine ∗hardware∗ running the Cloud algorithm.

www.synthtech.com/m520/cloud_hw.mp3

As usual, square-waves in the left channel, sine waves in the right.

This lashup uses the Xilinx S3Esk development board and the Analog
Devices ADuC7020 Mini-kit demo system. The two are connected through a
3-wire SPI interface running at ~500kHz clock rate, which means we only
get the oscillator frequencies updated at about a 100Hz rate. The ARM
reads two voltages and interprets them as frequency and spread. From
this it computes 16 oscillator frequencies and sends these to the FPGA.
The voltages are just 2 pots, so the demo is just "knob twisting". But you can
hear the various effects of the raw oscillators (no chaos or PWM or spectral
shaping).

The ARM we will actually use is the 7026, which has more ROM/RAM but uses the
same 'core'.

b) Indiana is still in the process of making up the ~400 kits left to ship. They
are scheduled to receive
more parts late tomorrow (mostly 1500 knobs) and by the end of the week should
have about 150 kits available to ship.
So, it's looking like these kits will start shipping out the week of the 13th.
The pacing item remains the panel
pots, I am calling Bourns this week to see if they can speed things up. There
are enough pots to make up around 240 kits
as of now.

c) On the MOTM-650 firmware front: the root cause of the remaining bugs has been
identified (timer issue) and
also the week of the 13th I am expecting shipments to resume. If, however, the
code takes longer I will ship the
current software.

d) I am shipping 17 assembled modules out this week.
