Hi Dieter,

It’s very simple. First you open up your Pulsar by removing 8 screws on the back. Gently lift up the back panel and locate the BD pcb inside your Pulsar.

First you need to remove the current BD PCB. Using a tweezer you need to release the four latches by squeezing them. Then you pull the BD board up by pulling on it equally on the top and bottom sides.

Install the new BD board carefully by pressing the opposite edges down equally.

The BD oscillator restart switch is in the bottom-left corner.
In the up position, marked as STAB, the BD oscillator will restart on each BD trigger. In the down position, the BD works in the original Pulsar mode.
To make the restart function work stable, ATT knob must be in the minimum or very close to it. REL must be short enough to decay before the next triggering.
Triggering velocity must be close to the maximum.
In some settings stability may also depend on TUNE knob position.

This is typical phase shifting that occurs when frequencies are close. It is normal.

Rare bug fixes! Nothing changed in the functionality.

No, you cannot adjust the volume of individual voices.

We can roughly adjust the volume by changing the signal mixing scheme by turning the 4th pot on the 6th page. Sometimes it gives results.

All Cosmos firmware updates are just rare bug fixes to make switching algorithms even smoother, everything else is identical. There were no changes done to the LED lights or anything else on Cosmos. Since the functionality remains identical we only provide the latest versions on our website and newly produced Cosmos units.

Hi Frank,

The updated firmware reduces audible clicks, that is all. The LEDs are yellow, what do you mean with that they change color? If you’d like to record a video to show us, feel free to email it to [email protected]

Thanks,

Hi Marc,

Early P23 do not have the reset MIDI function, this is why it likely does nothing for you.

The other behavior does not sound normal. Please send an email to Soma tech support at [email protected] with the serial number, an explanation of how you are trying to send MIDI messages and a video showing what you are trying to do. We will analyze what could be going on.

Thanks,

Yes it’s possible of course but needs a more complex invasion.

The simplest solution – just to pick up the signal from the middle pin of the VOL pot.

[SomaLabs]

It is about the X2 receptacle…

In the manual, it says: „doubles the capacitance of the storage capacitor“.

Now, does that mean that if I pass on a voltage from cell 1 to cell 4, but do not trigger it at the same time, the capacitor stores the value until the cell is triggered?

Yes the capacitor is a kind of simple analog memory. It stores the last voltage that was on the main capacitor just before the voltage on X2 got zero.

Or do I need to pass on any X2 value AND at the same time also trigger the cell?

You can consider these processes as independent

I tried to find out by experimenting but did not really come to a definitive conclusion.

Just think about the capacitor as an additional volume that connects to the main when you will put a voltage on X2.

And it doesn’t depend on is the cell is triggered or not

[SomaLabs]

Yes, it is possible.

The simplest way is to remove the voice PCBs and connect the corresponding pins with wires.

I recommend using shielded wires with a grounded shield to avoid crosstalk that the wires may cause.

Hi Mark,

Please send an email to [email protected] with serial nr and a video with clear audio showing the problem.

Cheers,

From the manual:

To clear all learned MIDI functions, simultaneously press the LRN buttons of BD, BASS,
SD and HHT modules (the four buttons at the bottom).

Pulsar works with 0-10v. If you are triggering from Eurorack, you are likely only sending max 5v. You need a stronger trigger signal most likely.

[SomaLabs]

Pulsar has unbalanced outputs, so as a rule of thumb it’s better to use TS jacks. 

[SomaLabs]

From the manual “The permissible volt-
age range connected to the inputs of the Pulsar is -20 to +20 volts. However, the effective operation of the input is limited to a range of 0 to 10 volts.”

So the answer is yes, to achieve full velocity, you need to send a 10v signal.
