FV-1 startup
Is there any specification (or real world data) on how long (after Vdd goes high) it takes for the FV-1 to load external EEPROM data?
I have other devices on the I2C bus.
How long before "the coast is clear"?

Partitioning power supply
I need to delay the startup of the FV-1 until other portions of the circuit are initialized so as to keep supply current low.
Is there a way to keep the FV-1 from drawing current (without removing Vcc)?

Headroom
How much headroom do you suggest for the FV-1?
What p-p input value will clip the ADC?
What sort of gain (loss) do you expect from most effect patches?

Variable notch filter
RE: http://www.spinsemi.com/forum/viewtopic.php?t=82 I have pared this code down and still have a useable, tunable notch. What I need to figure is the relation between the POT value (for frequency) and the actual notch frequency. ;Frequency control rdax pot0,1 ;get freq control rdfx p0fil,0.01 ;aver...

EEPROM address boundaries
What are the address boundaries for each effects patch?
I notice that most patches seem to leave some "blank space" (hex 00s).
The spaces seem to be 0x200 long.
Is this true?

Cascade Left and Right Channels
Is it necessary to include the low pass filter components when feeding left channel output to the right channel input of the FV-1?

modify specific EEPROM locations
I am fine with having the FV1 reload (under MPU direction)
Is there a way to disassemble the EEPROM code or otherwise know what location contains the value of any specific parameter (ie: delay time)

Additional Parameters
Is it possible to modify specific locations in external EEPROM to adjust additional parameters (ie: notch filter center frequency)?

Using PWM output of uP to drive pot inputs
With a simple RC filter on a PWM output from a uP, will the FV-1 accept the DC with ripple input?

Separate control of Left and Right
Is there any way to separately control the parameters of the left and right DSP channels?
