Ich suche jemanden, der sich meines kaputten Plan B "Milton" annimmt. Gegen angemessenes Entgelt natürlich, und muss nicht mehr unbedingt vor der Weihnachtszeit sein (obwohl das schön wäre). Habe ein paar Leute in US und UK kontaktiert, aber regional wäre natürlich am besten.
Wer's nicht kennt, das Modul ist ein 16 x 4 Sequenzer mit analoger Stage-Addressierung (also auch nutzbar als analoger Quantizer, Waveshaper oder nicht-linearer Sequenzer mit z.B. 64 Schritten, oder als Speicher für verschiedene komplexe Hüllkurven - westcoastig/ Buchlisch halt).
Milton malfunctions
Tested in a rack with six Wiard 300 modules and a new Hinton Full Power 2A PSU.
Clocking:
- When clocked straight (without stage select CV, reset or anything) it regularly skips or "limps" a step or several (happens roughly every to 10th to 20th round)
- Reset errors (always present except where noted):
Reset input fed by gate output #4 = acts like fed by #3
#5 is sometimes good, sometimes = #4
#8 mostly = #7, sometimes #6, sometimes #8
#12 = #11
#16 = #13
Pots:
- Pot 16 in row B is dead (knob turns as normal but output is always 0V)
Output jacks:
- Programmed Voltages, row C jack #2: has a positive offset from jack #1 (while they should be identical), whereas the higher the voltage per se, the higher the offset percentage, up to more than an octave when turned clockwise
- Row D jack #1: Stage 8 = chaotic fluctuation (at jack #2 it's ok so the problem is probably not in the D 8 pot)
Miscellanous:
- The Disable Gated Pulse controls don't seem to work properly: when switched off, an input CV of any level will not switch the Disable function on, and when the switch is on, an input CV will still not switch the Disable function off except when below 1.5V or so. So the CV input in practise doesn't work unless I invert and offset the CV first. This would take both halves of a Mixolator plus a DC source, like a joystick. Maybe I just don't get this section though.
- Programmed Pulse Outputs: the row B outs are offset by more than -15V (my voltmeter doesn't measure any lower). This still works when used to trigger the Envelator, or when fed into the slew limiters ("AR envelopes") on the WFC and CVCO (because these, too, work as rectifiers for negative voltages), but I'm wondering if they could damage something when plugged into somewhere else. I do know pre-2011 Sequantizers could be fried by negative input voltages and I haven't heard of any modern modules that use negative voltages as triggers.
There could be additional problems in the more sophisticated sections (like Async), but since I haven't studied Milton's theory in full yet I would not have discovered them yet.
PCB versions:
4 x rows: Rev 1.2/ Ken Stone
Main board: Rev 1.3/ Cynthia
Async Board: "Copyright PG 2004"/ ModCan
4 x Programmed Voltages (very small boards): the only labelling is PGR01, and they are combined on one piece of perfboard.
I was also asked about the make of the 4516 - it's an HFC4516BE by ST.
Wer zum Helfen erstmal eine Übersetzung braucht, schreibt mir bitte eine PM (die erreichen mich schneller als Antworten im Thread).
