Hi ppl,

I wonder if its possible to add a external in jack for using the filter 
on a external signal like my E-guitar as example. Does someone have 
already experience with such mod? And maybe there are pics how to make 
it?

Cheers
Tim

Well, already the filter with LFO control would be a very nice 
phaser. Im my case filter freq and reso would be enought as I d need 
that to change the reso freq of my active pickups (on passive there 
are easier ways). Less Hi tone would make a smooth distortion and 
adding Hi would sharpen the tone.

The Reso it self is part of a guitar tone but with more reso it 
would get a synth character.

Adding a ADSR on the VCF would rather make it to a autowah.

On the other hand i m already about to solder me a Moog and a Korg 
MS-20 filter to this matters.

Cheers
Tim

Never miss a thing. Make Yahoo your homepage.

DOH! I was sure no one would miss it. I guess I'll have to find a way
to keep chord mode.

If the only problem is how to access it, perhaps the button could cycle 
from chord memory to unison mode to off.

Sorry but what has the chord mode to do with a external in where I m 
able to apply the filter (and maybe some other parameters) on a 
external sound source like a E-guitar or a different Synth?

I just want to know where I need to add the hot of a 6,3mm jack to 
route it through the VCF and where I need to pick up the signal again.

I could rewrite the code to toggle between Poly and mono mode using
the Poly key. Another way might be to make the Poly key the selector
for Poly, Mono, Chord and Hold mode. Each time you press the poly key
would move you into the next mode. That would free up the chord and
hold buttons to be used for selecting global mode and extended
parameter entry modes (or other things if we decide to add more).

What do you all think?

I managed to finish the pitch "bending" part of the mono mode
portamento last night. Unfortunately, the results are not as good as I
had hoped for although I was not completely surprised at the result
that I got. The method I used to simulate portamento was to use pitch
bend (which is a true analog bend) to slide one semitone up or down to
track towards the new note. Once the  bend has moved the TG half a
semitone, the DCO's are reprogrammed to change to the note above or
below while simultaneously the bend is reset back to zero. This would
give the portamento effect by ramping the bend a semi tone and quickly
switching DCO semitones.

Well it works, and it gave me great joy to hear it working, but alas,
resetting the bend is a little slow and you can clearly hear the
oscillator output has a little glitch each time that the semitone note
change occurs. I now need to determine if the glitch is caused by the
master clock being incapable of tracking the output of the DAC when a
square wave edge change occurs in the bend or if the DAC sample hold
circuit is too slow. If it's just the sample and hold then I may be
able to reduce the sample hold capacitor to improve the highest
possible rate of change. If it is due to the master clock not being
able to change frequencies fast then I think we might be out of luck.
So much so that the only way to get good portamento would be to build
a new master clock that was able to slide the full five octaves.

Hi, it was written here yet, may be. 
Message 1260:   "...audio input instead of noise generator - in the 
concrete transistor Q5 (in schematics p800_2.
gif signed as "SELECTED").Removing of this transistor is not
necessary. You need only join signal wire on point between Q5,C25,and

The other people joined input to some other point, but I can not 
remember. Try to find in messages.

I, for one, would prefer to retain the chord memory mode. I like use 
it for playing 2-3 octaves of the same note in mono with one finger. 
It looks like you are leaning towards keeping it after all. Thanks 
for all your hard work.

But what about sequencer's STEP button ?

With sequencer's back switch in DISABLE position STEP button has no
function at all so i think maybe this button would be good for
enabling portamento.

I already have the step button doing triple duty. It gets us into
global mode and while editing parameter values, it gets us into
extended parameter editing mode.

So the step key is pretty busy now. LOL

Oops ! Sorry !

I didn't notice that. Silly me :)
So it looks like we have run out of buttons ;) !

================================

that would work, since the modes are (or can be) exclusive... probably not 
everyone on the list has a PC1600 (or similar), but i'd be happy as long 
as i can select the modes using standard MIDI CCs. do you think you'd be 
able to provide visual indication of which mode is currently selected?

==================

maybe you'll come up with a different way to approach the problem..?

even if it's glitchy, i'm sure it's still usable... i was just talking to 
tom (the guy who i made the first moog-slayer for) and he reminded me 
about a patch i wrote for him on a CZ-101... listening to it straight from 
the CZ it sounded kinda cold and very digital, but in the foreground of 
the mix and with some reverb (we probably used a BOSS SE-50) it sounded 
sweet and analog and warm and huge. years later it still impressed him. so 
i'd be interested in it even if it is glitchy...

and if you "fix" it in a later release, leave the option of using the 
glitchy version... seriously... one never knows what genres of music might 
be formed from an obscure glitch...

 		-- Adolf Hitler

Hi Atom,

I agree with everything you said.

i) I'll keep portamento even if it is glitchy.
ii) I'll change the Poly key to be the mode key so that each time you
press the Poly key you switch to the next mode (Poly, Chord, Hold,
Mono, Poly...).
iii) there will be CC's to change the mode too.
iv) for visual indication P for poly is already used so we need to
come up with a letter that would indicate portamento mono mode. I
thought "S" would work but it looks like a "5". Anyone got any
suggestions?

Further testing last night revealed that the bend is so slow to react
to changes at higher slide rates that the portamento rapidly turns
into stepped DCO semitone changes. So it sounds best at really slow
rates where you glide from one octave to another over a period of 5 to
10 seconds. Even then you can still hear the little glitches. My last
option now is to try to speed up the master clock reaction to bend
changes and try to improve the sample and hold circuit. I wish I had a
frequency counter and oscilloscope right now.

But, when I run into walls like this I take a break so that I can come
back to it with a fresh perspective so I think I'll leave it all alone
as I have other pressing work to do.

Wish those 5 boards would get here soon.

Mike.

I think that's a great idea! Simple and effective.

People spend a lot more than that on glitchy hardware. Look at the
SIDStation. It's a crashy glitchy mess but people still bought them :)

I want one of these for my MKII :)

i don't have it front of me right now, but are there dots on the display

oh no!!! not an overclocked poly-800!!!

i can just picture it in my head... liquid-cooled nitrogen kits for people

how many people spent several times that on a sid-station, with glitchy

True, true, true.  I'd love to hear this glitchy portamento -- it could
definitely be musically useful to the right people.

Alex,

I like your humour. :-)

If I ever buy a MKII I will look at the design and see if it could be
fitted into it.

But the kit only works in the EX800 and Poly MK1. It does not work in
the MKII. Sorry :-(

Mike.

Dave,

To be honest, I got a little disappointed with the glitchy portamento,
but your accolades along with everyone else have really boosted my
spirits again. The portamento works well enough as it is to be good
enough for the grungy square wavish type sounds because the odd
harmonics tend to mask the glitchiness. It's only when you filter low
that it gets a little annoying and overly noticaable.

I'm no professional video creator, editor, producer and my youtube
videos prove that point. However, I am definitely going to do a few
more within a week or two. At the time that I did the first dual LFO
video I didn't even have a way to save the extended parameters. So it
was very difficult to showcase a series of new patches. But now that
the extended parameters are able to copied from one patch to another
with the "write" key, all I need to do is sit down and do maybe 8 or
more distinct patches and I'll be able to put together a really nice
demo. Did I mention that my keyboard skills suck?

The Moog Slayer mod as it currently exists will continue to work
perfectly well with my kit. My kit goes nowhere near any of the analog
mods at all. The big future upgrade, which I have partially prepared
for with the initial upgrade kit, will include a couple of digital
potentiometers that will allow us to control the Moog Slayer mod from
software. That will allows us to plug the EG's and MG's directly into
the Moog Slayer pots (which will be repatched into the digital
potentiometers). Then, for all of you brutes who drilled holes in your
keyboard, we will just patch those potentiometers into a analog to
digital converter (or two) and assign them to controllers. The end
result will be that you end up with the moog slayer mod being fully
integrated into patches and controls as well as being able to use the
knobs to control the Moog Slayer mod or any other controller you feel
like twiddling with.

I really think that given about another 12 months of software
development, the Poly 800 and EX 800 with the Hawkins and Moog Slayer
modification will be considered a top rate synthesizer that far
exceeds the competitors of its time and will perhaps challenge some of
the existing instruments too.

This is fun!

Mike.

A clearer demonstration of the improved Poly-800's capabilities may

Pity...Now, if we could show the world the combined powers of both

Maybe you could find some already modded Poly-800 to do the trick?

and for everyone else, just plug in a delay or reverb to mask the

So you're saying we'll have more than one "data" knob to tweak parameters instead of poking 
the up and down value buttons??? If so...cooooool! =)

Do you mean using the sequencer as a free-form LFO/ modulation generator?
That would be awesome!

i think he meant using sequencer speed slider for parameter value input.

Oh, I forgot about the speed slider.  Well, that would be cool too :)

You could use it as a sequencer or arpeggiator and have a mode to use
the note values as modulation values for things like the filter (kind
of how a Korg MS2000's sequencer or Roland SH32's arpeggiator does)

I'd definitely like to try to make it work. 
Does anyone have a ROM image of the MKII? The biggest difference seems
to be the digital delay line instead of the chorus.

Does anyone have a copy of the MKII service manual or schematic?

Because that would be a big help in working out if the kit could be
fitted into it.

I once saw the inside of a Poly 800 MKII and it had a much larger ROM
installed and a totally brand new board where the ROM lived. The ROM
socket on main board had jumper cables running over to the new board.
It was quite a mess.

The schematic diagram of the MKII would put the question to rest.

Mike.

Hi Mike,
This is partially why I uploaded the Service Docs and Schematics to 
the files section. You are right the ROM is on the digital delay pcb.

> Well, the initial kit is not going to include anything more than
some extra spaces on the PCB for additional chips. What those chips
turn out to be is going to be up to us. I figured that we would
probably put a few digitial potentiometer chips on there and then a
AtoD converter and demultiplexer. That would give us control knobs.

Yeah, I knew the first kit wouldn't include the digital pots...I'm
just thinking ahead ;-)

*rubs her hands in anticipation* Oh, Poly800 sitting there in my
closet, do I have plans for you...

Thank you for all your hard work, Mike. I can't wait for all this to
come together!

Phoebe

If necessary, i can pop mine open and take pictures or trace things.

The MS2000 has a kind of modulation sequencer where you can set steps
to values and send it to a modulation source (filter cutoff,
resonance, volume, etc). It can also be used to sequence changing the
osc waveforms. (Korg calls it Wavesequences, some of their older gear
had it too)

Dunno if that's beyond the scope of this mod but it is a sweet feature.

Hi, I have the MkII service manual (hard copy only) as well as 2
Poly-800 mkIIs. If you want me to check something lemme know...

Mike.

I think the MK2 might actually be a potential candidate for this kit

would be a real gamble.
