Re: [oberheim] trying to diagnose generall weakness of my matrix 12

i definitely have a reliable monitor system/room/.. as well as other synths which easily shake the room without the aid of eq/compression.

"Poor low frequency response can be caused by coupling capacitors drying out, but this isn't usually the first place to look, and unless you have all the information, test equipment, tools,expertise and parts"

what is the first place to look? I have scope, multimeter, proper soldering/desoldering rig.. my expertise is a solid medium (i've fixed juno106 problems (pots, sliders, chips, outputs, leds, I've never rebuilt a power supply)..

i'm in Brazil.. shipping tech in and out of the country is a big hassle so I'd prefer to fix things here myself...

It's possible that the samples you are comparing it to have undergone change after they left the instrument, either accidentally or by design.
EQ is the first thing people try, but isn't usually the right solution.
Compression is usually the next thing, but........ditto.

If you have a known good audio monitor system a working xpander should make be able to make the dust fly out of the speaker cab ports. Just like one of your CDs turned up loud.

Poor low frequency response can be caused by coupling capacitors drying out, but this isn't usually the first place to look, and unless you have all the information, test equipment, tools,expertise and parts you need, it could end badly.
The internet is encouraging us towards this kind of activity, but it's not a sensible option for the inexperienced, who can be prone to mis-diagnosis in the first instance, and careless work these fine instruments do not deserve.
It's possible to degrade the frequency response by shunting the output of most audio devices with a low impedance.

thanks for answering...

i find myself always wanting to boost the low end... also normal?

it is normal for there to be a world of difference between RES=62 and RES=63??

Matrix-12 / Xpander are great synths, but they don’t have balls like Memorymoog / Prophet-5, they have boobs instead…

Resonance to 63 means filter self-oscillation and yes this is normal.

Hello

I have a Matrix 12 (Voice 1.4) (Main Software 1.1)

I like it but when I listen to online samples they sound much better..

Mine seems to lack "balls".. I have no trouble with any tuning.
But my low end doesn't seem to be there and many of the factory presets don't really impress.

Once thing I've noticed is that when I adjust the VCF resonance, there is a HUGE difference between 62, and 63.. in fact resonance=63 is the only time the synth grows a pair... 0-62 is wimpy, 63 is burly.

Is this normal?

I really want to get this thing sounding good!!!
