I have two MAMs that deliver a full belt each so my system can deliver say 40 pcs/sec right now but my level requirements are higher. I'm dying trying to make an reliable storage system but I'm crashing agains a wall.

My idea to control the storage was:

1. Storage start with two outputs, 0 on the left and null (which I convert to 0) on the right.
2. As storage itakes its firts piece the right output becomes the shape in it.
3. I wait untill the storage is full so the left input becomes a 1
4. If left is 1 and right is not 0, I open the filter and shapes run through.
5. When storage returns to the starting position I close the gates

BUT THEN

In step 4, as the first shape comes out of my storage, the left 1 becomes a 0 for a brief time, as the storage isn't full between the moment the shape comes out and the next shape in the input belt comes in. That messes all my logic because as a result the outputting filter starts constantly opening and closing not allowing me to reach the required shapes per sec to beat the level.

I need a way to control the filter to be open constantly since the left becomes 1 for the first time (and then no matter what happens to it) until the right output is null.

Can someone provide me some help on it or give me some tips on controlling the storage system?
