[1691] Stompbox Patents

Date: December 11th, 2014 | Comments : none | Categories: DIY.

I have added the Maestro Fuzztone patent to my page of effects related US patents.

I often see users comment in online fx forums that you cannot patent effects pedal circuits, which is not true, as evidenced by the many patents I have listed on the US patents page.

[1654] Mini vs Mos Distortion

Minibooster-Mosfet distortion graph

I measured the distortion components of a mini-booster and mosfet boost for comparison.

Argggh! The graph above is not accurate. I was connected to the wrong signal generator and was getting results that were too noisy and distorted! The boosters do much better than the previous graphs indicated.

Check out the updated article in the Lab Notebook.

EHX Part 15 compliance

Over EIGHT years ago, I posted a note over at DIYstompboxes about testing requirements for digital devices, including guitar effects pedals. This subject has come to attention more recently as several manufacturers have been fined large sums of money for not complying with the rules.

[1604] Install EZ Drummer 2 on Windows XP

Date: May 21st, 2014 | Comments : [5] | Categories: DIY.

Proceed at your own risk! You need a Microsoft program called orca.msi     Get it here or here.

Install orca and then use it to modify the settings in the EZdrummer2_32bit_install.msi (or EZdrummer2_64bit_install.msi). There are other Msi Editors that can do the same job, but I used Orca.

Load the EZdrummer2 installer into orca and then search for VersionNT>600

VersionNT>600 is only found once in the EZD2 installer. Change that entry to VersionNT>500 and save (only work on a copy of the installer!)

Once the LaunchCondition has been changed to VersionNT>500 EZD2 will install on XP.

I did this last night, authorized my new EZD2 online at Tootrack’s site and then loaded up a Reaper project that already had EZD in it. It worked like a champ.

As soon as you have EZD2 open in your first project, you will need to go to the Menu in the top right of EZD2 and rebuild the database. Also, check Toontrack for upgrades to any extra drum packs you have purchased.

Proceed at your own risk! This worked for me but it may not work for you. Only work on a copy of the installer msi!!! Toontrack will (probably) not provide you with any support for use on XP.

Good luck, Jack
