Request for low cost linear fm

Request for low cost linear fm

2009-05-18 by pfichoux

Dear Mr Doepfer,

I'd like to see a low cost VCO designed specifically for lin fm. Also, a filter with linear fm could be great.

I know that the actual trend is for big modules packed with features like your brand new A-111-5.

But for cost and size reasons, I'd rather buy dedicated and narrow modules.

Don't you think it could be possible to mount 4 pot and 4 mini-jack sockets in a 6 HP panel ?

Best wishes,

Pierre

Mounting one of the standard A-100 potentiometers next to a miniature jack
socket as close as possible takes about 33-34 mm. The width of a 6 HP panel
is only 30 mm. To reduce the width of the front panel the elements have to
be arranged on top of each other (like the new A-183-x modules).

Best wishes

Yes ...

4 pots on the top and 4 mini jack sockets on the bottom. Like an A-111-5 slice, or a mini MOTM.

Most of the time, I use the same waveforms. I don't think it is that silly to consider dedicated designs (like one sine-tri for lin fm and another one, saw-square, for hard sync). With a single A-110, I'll never ever use sync + fm + PWM at the same time... I sware !-)

Today 3 A-110 are 30 HP. The same space could be packed with 5 VCO (perhaps for the same price ?-) ! Humm ... tasty ... "bonne cuisine" ... "et voilĂ " ...

Best,

Pierre

It's true that several complex modules have been added to the A-100 series
over the last couple of years, but at the same time some very simple and
basic modules have been added to the range - like the trigger combiner,
manual trigger, offset generator and so on.

Sorry if this next section sounds a little bit too much like that teacher we
all loved to hate. Anyway, even though I would actually like to see a simple
and cheap VCO, there's a very good reason this might not happen. The cost of
developing a new module dictates that only modules that have a good chance
of turning out a profit will actually be developed - and a new, simpler and
cheaper VCO would compete directly with the A-110 so chances are that each
unit sold would mean close to one less A-110 sold, thus cutting into
Doepfers profit margins. Sure, someone might buy 3 of the simpler VCO's
instead of two A-110's but Doepfers profit on that sale probably wouldn't be
much higher, so I can't see where the extra sales that should cover the
development costs would come from.

Finally, one of the joys of Euro format modulars like the A-100 is that you
can mix and match modules, so you may want to have a look at the MFB Triple
VCO - it looks mighty good at a very affordable price, but I must admit that
I haven't bought one yet so can't comment on how well it works in actual
use. Take a look at

Happy patching,
Silas

Nice to read you Silas.

About big modules, I do agree with you, most of Doepfer modules are thin. A-111-5 wasn't a good example because it's a synth on it's own.

The worst examples I have in mind are ZO and AFG. So many features you cannot use all together unless you want to make noise with a several hundreds Euros/Dollars module.

I do request because I don't understand why I have to pay more than 200 Euros for lin fm (I'd rather buy a DX-7 or an FM-8 plug-in).

Furthermore, if Doepfer's catalogue is packed with filters*, there aren't so many VCO...

Last, I would like to say that even with 8HP modules, I rarely use all the 5 inputs and 5 knobs at the same time.

Best,

Pierre

PS : I think I'll give it a try next winter (DIY)

Pierre, also remember that you can modify the a-110 to have linear FM - 
the pins are available on the circuit board, it should be quite an easy 
thing (a jack and a knob or so).

Andreas.

Hello

> Pierre, also remember that you can modify the a-110 to have linear FM - 
And once again: please keep in mind, that analogue VCOs (even with sine 
core) will never provide FM like a DX7 does. FM is that much sensitive 
to detuning. Detunings, which are completely bearable for subtractive 
synthesis, will complete do the kill-joy in FM.

Hi Andreas,

Did the mod yesterday evening (connected the cv2 input + pot to the lin fm optional input, AC coupling). The sound is ok but I can't do truly metallic sounds.

I wish there was a way to improve it.

Hi Florian.

I know there is a difference between DX-7 and analog fm.

Thank you both for replies and tip.
