- Check the LSynth's base path in your MLCad.ini file.
- You run LSynth and see a command prompt box flash (or stay depending on computer speed) stating the following "C:\Users\(part of your username here) is not recognized as an internal or external command, operable program or batch file. The system cannot find the path specified." and also get NO Synthesis as well as the dialog box above. Possible cause - MLCad is unable to access the LSynth application folder due to a symbol (ie. @#$%^&*) in your username.
Solution - Install MLCad along with LSynth onto another user account with a standard user name, create an account if needed. If it fixes the problem you can transfer all your files to the new user account.
NOTE! You can NOT just change your user name in the user account settings. You need to make a change in the windows registry to change all the associated folders. Applications that are not integrated into the Windows system may need to be re-installed. ie Java Programs.
- How many constraints did you place? Two is the absolute minimum number. LSynth will process your file and you'll see the SYNTH SYNTHESIZED BEGIN and SYNTH SYNTHESIZED END meta statements in your file but since you didn't provide enough data no synthesis can be calculated.
- Were your constraints visible before you performed the synthesis? If LSynth cannot "see" your constraint parts it cannot do any maths on the path.
- Modifying the color in the LSynth meta command you might modified the meta itself by mistake and LSynth doesn't no longer recognize the statement.
- Check the order of meta command and constraints in the file parts list, especially the LSYNTH SHOW command. Band type synthesis have additional requirements to work properly: counter-clockwise order, line-up, tangent statement.
