Your help is greatly appreciated, thanks!!
The external signal is attenuated by the "GAIN" control and then fed "through" the piston using the currently selected wavetable as a lookup. So, instead of using the Internal section's ascending sawtooth waveform to address the waveform memory, it uses whatever you put into that jack. Use a sine wave for effects like the Buchla 259e.
Patching this section is straightforward - oscillator into the EXT IN jack, audio coming out of the EXTERNAL output, CV modulating the GAIN parameter. I recommend using any leftover oscillators in your patch with this feature, as it's a convenient way to get an interesting waveform out of something else.
I've been getting excellent results plugging all sorts of things into the external input... never having had my hands on a buchla I was wondering what aspect of a 259e is replicated by feeding it a sine wave? I mean, I'm doing it right now and it sounds all kinds of awesome, I know that much

The "gain" knob functions much like the "warp" control on the 259e, and certain waveforms give you similar sonic results if you use a sine wave as input (the synthesis functions being performed are very similar in that case). The red and green waveshaping modes on the Hertz Donut are intentionally reminiscent of my favorite tables from old revisions of the 259e using this same variable-gain waveshaping scheme (red 6 and one of the green ones).
My PH mk2 just started behaving weirdly, first it failed to power up even while everything else in my Doepfer LC6 did power without a problem. I did some module moving on this rail right before powering up but didn't touch PH.
After a while it started showing some symbols on the screen. First it was one "F". Then two "8"s. Then just a part of a symbol. I tried powering it up on a Tip Top Uzeus, same result.
Then it started flashing the screen for half a second after powering up and then blacking out.
Anyone else had this problem? It'd be a real shame if it just died like that.
UPD. I just noticed that it does produce a sound even in this state. Both internal and external outs are the same sawtoothy sound. Ignores all controls. Range button is red.
Never heard of a PH unit just dying like that. Check to see that the voltage regulator (small green board) is consistently putting out 3.3V, that part may need replacement. Reloading the firmware may work as well - contact support@theharvestman.org to arrange service if you're still having trouble.

Did you ever figure this out? About to buy the expander and some ROMs, but also confused about the 2 extra slots?
I went ahead a bought the expander B. Smith expander rom set and the board. Should be getting them sometime later this week. Does anyone know what to do with the extra slots if one does not have access to extra ROMs?

B. Smith now supplies two more ROMs. I bought the full ROM set directly from him (you can also buy just the extra two). He posted about it somewhere around here.....

I just want to say a great big ol' THANK YOU SO MUCH to everyone who posted demos in this thread - they really made me pull the trigger on the Piston Honda. And now it's sitting in my rack. And I'm completely blown away!
tommygee wrote:Is the wave shaper in PH mkII identical to the wave shaper in the Hertz Donut mkII ?
No. The PH is a wavetable oscillator, meaning the wave shaping comes when moving from wave to another, while the HD's waveshaper takes a basic wave (like a sign) and shapes it in different directions.
So Ive got myself a pickit2, but I am having issues doing the firmware update.
I've tried this on 2 different PC's, both running windows 7, dont have anything else to run it on.
First I downloaded the new version of MPLAB(3.20) and on both machines it does not see the pickit2 connected at all.
Saw that the pickit2 originally came with v8.70 so I downloaded that and now it seems to see the pickit2, but I am getting the following:
First I get a pop up with:
PKWarn0003: Unexpected Device ID: Please verify that a PIC18F452 is correctly installed in the application (Expected ID =0x420, ID Read = 0x0)
Then this in the PiCkit 2 box:
Initializing PiCkit 2 version 0.0.3.63
Found PiCkit 2 - Operating System Version 2.32.0
Target Power not detected - Powering from PiCkit 2 (5.00V)
PKWarn0003: Unexpected Device ID: Please verify that a PIC18F452 is correctly installed in the application (Expected ID =0x420, ID Read = 0x0)
PiCkit 2 Ready
Now if I import the firmware hexfile, it shows up in the BUILD header, but if I hit the Program Target Device button I get the following:
First I get a pop up with:
PKWarn0003: Unexpected Device ID: Please verify that a PIC18F452 is correctly installed in the application (Expected ID =0x420, ID Read = 0x0)
Then:

Problem is, none of the instructions on the harvestman site match what I am seeing in either the newer software or the older one, the buttons and functions he notes are not there, and I cannot tell if the firmware has been transferred or not? My unit always booted to x and y lit, but I know I got it long before the newest firmware was released, so that isn't telling me anything either.
Can anybody tell me what is going on based on above? Did it transfer? Am I doing something wrong? I've looked around in the interface and I see nothing related to any settings for the PKWarn0003: Unexpected Device ID: Please verify that a PIC18F452 is correctly installed in the application (Expected ID =0x420, ID Read = 0x0) I keep getting either
Would really appreciate some help to get this sorted

Not sure if this helps, but this is PIC info for another module:
I've noticed that before, but I believe it's tied to the interpolation. I remember noticing no changes in sounds at the extreme ends with interpolation on, but when turned off I could hear that last (or first) waveform clearly.
I usually leave interpolation on for X and Y, and off for Z, that seems to be the best middle ground.
ianross wrote:Can you guys confirm that you have similar behavior. Figured I could get a quick answer here.
Some combinations of banks don't have a new waveform which seems strange. For example try this:
set X Y Z to 0 0 0
Now move Y or Z from 0 to 1 (but not both)
The wave is the exact same on mine. Is this the same for everyone?
